elevating device can result in personal injury or equipment damage.
Do not work on this product using live-wire operation. Be sure to turn off the power before performing any work. Otherwise, electric
shock can occur.
Do not apply water or oil to the brake. Reduced brake torque can result in falls or runaway accidents.
Overhauling of the reducer requires skill, so be sure to send the product to the specialty plant of Tsubaki E&M.
(Transport)
Never stand underneath the product while it is being lifted for transport. Falls can result in personal injury.
(Wiring)
Connect the power supply cable according to the wiring diagram in the terminal box and the instruction manual. Otherwise, electric
shock or fire can occur. (If the terminal box does not have a wiring diagram, insulate the connectors properly.)
Do not forcibly bend, pull, or pinch the power supply cable or motor lead wires. Otherwise, electric shock can occur.
Ground the earth terminal properly. Otherwise, electric shock can occur.
Be sure to ground the product and install a special ground fault interrupter for each product. Otherwise, electric shock can occur.
Install a motor protection device for each product. Problems can result in a risk of fire.
Be sure to use the AC source listed on the motor nameplate. Otherwise, motor burnout or fire can occur.
(Operation)
Do not operate the product with the terminal box cover removed. After performing work, install the terminal box cover to its original
position.
Never approach or touch the shaft or other rotating parts during operation. Catching and injury can occur.
Be sure to turn off the switch if a power failure occurs. Unexpected resumption of power can result in injury or equipment damage.
(Daily inspection and maintenance)
Never touch the shaft or other rotating parts when maintaining or inspecting the product during operation. Catching and personal
injury can occur.
Do not remove the pressure vent during operation. High-temperature lubrication oil can splatter, creating burns.
When inspecting the gear tooth surfaces while stopped, properly prevent the drive and driven equipment from rotating. Catching on
the gear meshing parts and personal injury can occur.

[ 2 ] Transport
Danger
Never stand underneath the product while it is being lifted for transport. Falls can result in personal injury.
Caution
(Transport)
Be careful when transporting so as not to drop or overturn the product. Be sure to use lifting hardware when available. Avoid lifting the entire
machine by the lifting hardware after installing the machine. Breaking of the lifting hardware, falls, or overturning can result in injury or
equipment damage. Before lifting the reducer, check the load on the nameplate, packaging, external drawing (specification and delivery
drawings), or catalog. Do not lift a reducer that exceeds the rated load of the lifting equipment. Breaking of the bolts, falls, or overturning can
result in injury or equipment damage.
Be sure to use the eye-nut on the top surface of the housing (fastened with a hex bolt) when transporting the reducer. Never hook
wires or slings to the input/output shafts. Doing so may cause unexpected load to the shaft/bearing and shorten the life of the reducer
or cause a malfunction. If the reducer comes with a motor, use the lifting hook on the motor as well to keep it balanced while lifting.
Note 1)
EWJ25 to 42, and EWJM42: No through holes on the top surface of the housing. Move by hand.
Note 2)
SWJ25 to 63, SWJM35 to 63: No lifting bolts provided. Move by hand.
[ 3 ] Installation
Caution
Do not place obstacles that can block ventilation around the reducer. This can prevent cooling and cause overheating, resulting in injury or fire.
Never place objects on or hang objects from the reducer. Otherwise, injury can occur.
Do not touch the key grooves, such as the shaft end or inside diameter of the reducer, with a bare hand. Injury can occur.
When using the reducer with food processing machines, especially equipment that is affected by oil vapor, install an oil pan or other protective
device in case of oil leaks in the event of a malfunction or the end of operating life. Oil leaks can result in product faults.
The area of installation should have an ambient temperature of 0 to 40°C, be well-ventilated, low in humidity, and have little or no dust.
Avoid use in areas with corrosive, explosive, or flammable liquids and gases.
If the reducer is to be used outdoors, furnish a cover or similar protection to avoid direct exposure to rain.
(1)
(2)
When installing or removing the reducer from the driven shaft, make sure to shut off the power source before working.
Always use the lifting bolt on the top surface of the reducer housing when installing or removing it from the driven shaft. Never
hook wires or slings to the input/output shafts.
(3)
Make sure the reducer is balanced and stable when installing or removing it from the driven shaft. Working with the reducer in
an unbalanced position is extremely dangerous as it may turn over. Always maintain the reducer in a stable position.
(4)
Models SWJ25 to 63 and SWJM35 to 63 do not have lifting bolts. Hold the reducer with both hands to keep it steady and
parallel to the driven shaft while inserting or removing it from the driven shaft.
3-1. Solid output shaft type
Reducers with a solid output shaft are either foot-mounted or flange-mounted (SW/SWM80 and later).
3-1-1. Foot mount (EW/EWM/EWJ/EWJM)
Confirm whether the installation is standard.
If the installation is non-standard, refer to the outline drawing or contact us as the volume of lubrication oil and the method of
lubrication differs from the standard design.
Install on a smooth flat installation surface that can easily withstand the weight of the equipment. The installation angle should
be within ±1°.
Use bolts compliant to JIS strength class 10.9T for installation.

3-1-2. Flange mount (solid output shaft type EWJ25 to 42/EWJM42/SW80 to 200/SWM80 to 200)
Mount the reducer using the flange side of the housing. Observe these points.
Solid output shaft SW80 to 200/SWM80 to 200
(1) Use the taps on the flange side of the reducer housing and use the spigot facing on the housing for positioning.
(2) Install the reducer by adjusting the radio runout, and the connection and angularity of the input/output shafts.
(3) Use bolts compliant to JIS strength class 10.9T for installation. Refer to the following table for recommended bolts.
(Bolt sizes in table: depths are tapping depths.)
Note) If the input/output connections are done without utilizing the spigot facing, tightening the bolts on the flange surface may
cause an unexpected load on the shafts/bearings which may shorten the life of the reducer.

3-2. Hollow output shaft type
There are three ways to prevent the reducer from rotating: torque arm mount, flange mount, and foot mount (EW-H only).
(1) Before inserting the driven shaft into the hollow output shaft, make sure the outside of the driven shaft and the inside of the hollow shaft
are free of scratches and dust.
(2) To make insertion easier, apply grease or molybdenum disulfide to the driven shaft.
(3) If the shafts fit very tightly, help the hollow shaft slide smoothly by tapping its opposite end with a plastic hammer. When you do this, be
careful not to damage the oil seal.
(4) The hollow shaft keyway is finished to New JIS standards for normal grade keyways. As for key length, refer to the following table,
Recommended driven shaft lengths.

3-2-1. Installation/removal of torque arm
1. Installation procedures
Note) Avoid using a line shaft to connect reducers with a double input shaft.
(1) Fix the torque arm to the reducer with bolts.
Note) If the torque arm is purchased from TEM, use the attached bolts. If you make the torque arm, use a bolt strength class of 10.9 or
equivalent.
(2) Insert the reducer onto the driven shaft.
(3) Fix the reducer to the driven shaft in the axial direction.
SWJ25 to 42: TEM recommends fixing the end plate on the end of the output shaft. (Figure 1)
SWJ50 to 70, SW80 to 200, EW80-H to 200-H (hollow output shaft): TEM recommends fixing the stop ring and end plate
by using the stop ring groove on the hollow output shaft (Figure 2). (See the "Detailed dimensions of hollow output shaft"
Technical Data in the catalog.)
(4) After finalizing the installation position of the reducer, fix the torque arm to prevent the reducer and driven shaft from rotating.
Provide sufficient room so that the torque arm is free to move in the axial direction.
Note) Do not fix the tip of the torque arm before fixing it to the reducer. Doing so may damage the reducer. Follow the work procedure as outlined
here. (EW80-H to 200-H are foot mount types. After fixing the output hollow shaft and driven shaft, set up the position of the bearing which
supports the driven shaft.)

Lift the reducer using the lifting bolt.
Loosen the end plate bolt which fixes (axial direction) the reducer to the driven shaft.
Remove any attachments on the tip of the torque arm, which stops the shaft from rotating, so that it moves freely.
Remove the hollow output shaft from the driven shaft while preventing from applying excessive force between it and the
housing. Prepare a draw plate (Table 1) and jack bolt (Table 2). Removal is much easier when the draw plate is used as
shown in Figure 3.

3-2-2. Installation/removal of flange mounting
1. Installation procedures
Mounting the reducer to the driven machine (if radial load does not affect the reducer)
(1)
Insert the reducer onto the driven shaft.
(2)
Use the taps on the flange surface of the housing for mounting.
(3)
SWJ25 to 42: Use the holes on the flange surface of the housing to bolt the housing in place.
Refer to the table and figure on page 12 for mounting information such as bolt size, dimensions, and pitch.
Use the spigot facing on the housing for positioning. (SWJ25 does not have a spigot facing.)
Note) The end plate is not necessary for flange mounting. If the end plate is used to fix the hollow output shaft, the bearing may be damaged
due to the thrust to the bearing on the hollow output shaft.
Mounting the reducer by its flange to the driven machine (if radial load affects the reducer)
(1)
Insert the reducer onto the driven shaft.
(2)
Adjust the radial runout of the driven shaft, and install the reducer so that it is free in the thrust direction.
(3)
Use the taps on the flange side of the reducer housing while using the spigot facing on the housing for positioning.
(SWJ25 does not have a spigot facing.)
(4)
After fixing the reducer, fix the driven shaft in the thrust direction.
Note) If the driven shaft is fixed in the thrust direction first, the bearing may be damaged due to the thrust to the bearing on the hollow output
shaft.
2.
Removal procedures
The reducer is mounted to the driven machine (if radial load does not affect the reducer)
(1)
Loosen the flange bolts that fix the reducer to the driven equipment.
(2)
Remove the hollow output shaft from the driven shaft while avoiding applying excessive force between it and the housing.
Prepare a draw plate (Table 1) and jack bolt (Table 2). Removal is much easier when the draw plate is used as shown in Figure 3.
The reducer is mounted by its flange to the driven machine (if radial load affects the reducer)
(1)
Hold the driven shaft steady in a balanced state.
(2)
Loosen the flange that fixes the reducer to the driven equipment.
(3)
Remove the hollow output shaft from the driven shaft while avoiding applying excessive force between it and the housing.
Prepare a draw plate (Table 1) and jack bolt (Table 2). Removal is much easier when the draw plate is used as shown in Figure 3.
14
3-2-3. Installation/removal of foot mounting (EW-H hollow output shaft)
Make sure the driven machine and reducer are aligned properly by referring to these installation procedures: Section 3-1-1. Foot
mount; Section 3-1-2. Flange mount; Section 3-2-1. Installation/removal of torque arm. Improper alignment can cause unexpected
loads which may lead to breakage of the shaft/bearing.
[ 4 ] Connection
Caution
When connecting the reducer to the motor and load, be careful of the alignment, belt tension, and parallelism of the
pulley. When direct coupling, be careful of the direct coupling accuracy. When setting a belt, adjust the belt tension
correctly. Before operation, securely tighten the pulley and coupling tightening bolts. Otherwise, launching of parts
can cause injury or equipment damage.
Provide a cover so that rotating parts cannot be touched. Otherwise, injury can occur.
When rotating the reducer separately, remove the key temporarily attached to the output shaft. Otherwise, injury can
occur.
Check the direction of rotation before connecting to another machine. A difference in direction can result in injury or
equipment damage.
4-1. Verifying the direction of rotation
Worms are always cut to a right-handed helix. Verify the rotational direction of the input and output shafts.
4-2. Connection
(1) Connecting to the input shaft and output shaft of the reducer
• Do not apply impact or excessive thrust loads to the shaft when installing pulleys, sprockets, or couplings to the reducer input/output
shafts.
• Align accurately. Refer to pulley, sprocket, or coupling catalogs/manuals to ensure alignment accuracy.
• Shaft eccentricity, and radial and axial loads that exceed allowable values may cause vibration or noise, possibly shortening gear,
bearing, and shaft life.
(2) Motor handling when the motor is installed by the customer (applies to motor handling code “Y” for the EWJM/EWM/SWJM/SWM Series)
• Couplings are not used to install the motor to the input shaft of the reducer, because the input shaft is hollow.
• Reducer input shaft bores and keyways are machined for the specified motor capacity. Use the key supplied with the motor.
• Take safety precautions when following the procedures below.

[ 5 ] Lubrication
Worm gear reducers are filled with lubrication oil and sealed before shipment. They can be used as is without having to add oil.
5-1.Recommended lubrication oil Daphne Alpha Oil TE260 (IDEMITSU)
• Lubrication oil is vital to reducer capacity, life, and efficiency. Use only lubrication oil recommended by TEM. Do not mix the oil with
other brands.
• Daphne Alpha Oil TE150 is recommended for reducers that have trouble starting in low temperature environments with an input
speed of 1500 r/min or faster.
• Do not mix with other lubrication oil. This can result in reduced performance and shortened operating life.
• Single reduction gear reducers running at an input speed of 500 r/min or slower can benefit from longer life by switching to Daphne
Alpha Oil TE380.
• Do not change the brand of lubrication oil. Contact your distributor or TEM to have the lubrication oil changed.
• Contact your distributor or TEM dealer for information about Daphne Alpha Oil TE.
Note) Contact us if the ambient temperature is below -10°C or above 50°C.
5-2 Approximate oil volume
• Even with the same size reducer, the oil volume varies depending on the reduction ratio. Use the volumes in the following tables as a
guideline, and always check the oil volume with the oil gauge. (The oil volume is correct when it can be seen in the oil gauge when
the reducer is idle.)
Note) No oil gauge is provided on the EWJ/EWJM series and SWJ/SWJM series.

5-3. Replacing the lubrication oil
(1) Lubrication oil is vital to reducer capacity, life, and efficiency. Use only lubrication oil recommended by TEM.
(2) It is not necessary to replace the oil for the EWJ/EWJM series and SWJ/SWJM series. However, if the lubrication oil deteriorates
significantly due to usage conditions, it can be replaced for reassurance.
(3) Follow these guidelines to determine when to replace the lubrication oil for models EW/EWM80 to 200 and SW/SWM80 to 200:
• First change: 1000 hours or three months after starting operation, whichever comes first.
• Subsequent changes: 5000 hours or one year depending on operating conditions, whichever comes first.
• Replace the oil earlier if there are signs of significantly reduced oil performance (viscosity, color, etc.).
• It is easier to drain oil while it is warm, such as immediately after operation. However, hot oil may cause burns and is extremely
dangerous. Allow the temperature of the housing to cool to 40 to 50°C before draining the oil.
• Even when the oil level falls below the oil gauge when changing the oil or when the oil has decreased due to whatever conditions, the remaining
oil will occasionally appear to be remaining at the lower end of the oil gauge due to surface tension. Therefore, in managing the oil level, please
check that the oil level is maintained in the middle of the oil gauge.
17
• TEM recommends flushing the inside of the housing with the new oil.
Note) Do not mix the oil with other brands.
Note) No oil gauge is provided on the EWJ/EWJM series and SWJ/SWJM series.
5-4. Supplying grease (Semi-standard package)
• If the mounting direction of the reducer causes the shaft bearing to be face up (where the bearing is located above the oil level), the
bearing must be greased periodically. (Applicable to sizes 80 and above, excludes sizes 70 and below.)
• Models that must be greased are provided with a tapped hole for mounting a grease nipple.
(This is indicated on the external drawings (specification and delivery diagrams) as a grease nipple. See the external drawings
(specification and delivery drawings)).
• A stopper plug (M6 fine threaded hex bolt) is mounted before shipment to prevent oil leakage during transport. Replace it with the
grease nipple supplied with the reducer during installation or before operating. Note, the bearings are greased before shipment.
• Follow the procedures outlined below to supply grease every 1000 hours of operation.
Step
1
2
Replacement procedures
Add grease when the machine is stopped.
Supply grease from the grease nipple located on the top of the housing. Use only the recommended grease.
Note) Do not over grease. Doing so may cause the reducer to heat up, and cause the lubrication oil to deteriorate prematurely.
Grease nipple size: A-M6F

[ 6 ] Operation
Danger
(Operation)
Never approach or touch the shaft or other rotating parts during operation. Catching and injury can occur.
Caution
(Operation)
For a specification with a fan cover, do not insert your hand in the fan cover. Otherwise there is a risk of being caught in those
parts resulting in injury.
The reducer becomes very hot during operation. Be careful not to touch it with your hands or body. Burns can occur.
If a problem occurs, immediately stop operation. Otherwise, electric shock, injury, or fire can occur.
Do not use at above the rated load. Injury or equipment damage can occur.
Do not loosen the oil plug during operation. Lubrication oil can splatter, creating burns.
When reversing operation, be sure to bring the reducer to a full stop before starting reverse operation. Plucking can cause the forward-reverse
operation to damage the reducer or equipment.
The reducer is filled with lubrication oil and plugged before shipment. Replace the plug with the supplied pressure vent before use.
Note 1)
Note 2)
Otherwise, oil can leak from the oil seal due to high internal pressure.
EWJ/EWJM series (including double reduction models) and SWJ/SWJM series: A pressure vent is not necessary and can be
used as is.
6-1. Double checking before operation
6-1-1. Checking the reducer
Upon completing the installation, check the following prior to operation:
① the reducer is filled with the correct amount of lubrication oil. (The amount of lubrication oil is correct if it can be seen in the oil gauge.)
② the pressure vent is installed. (If the reducer mounting direction is a special design and comes with a grease nipple, install it as well.)
③ the reducer is connected properly to the driven machine.
④ all mounting bolts are fully tightened.
⑤ the direction of rotation is correct.
For reducers equipped with a motor, also check the following items:
an appropriately sized earth leakage breaker and overcurrent relay is wired into the motor circuitry.
all wiring is correct.
the motor is properly ground.
Make sure the equipment incorporates failsafe measures to prevent accidents from occurring during operation of the reducer, or in the
event the reducer stops working properly.
6-2. Trial run
No trial run is made prior to shipment. For best results, operate the reducer for roughly one day under 1/2 to 1/3 load.
6-3. Load
Loading the reducer above its rated capacity can affect its life and result in damage.
Do not load the reducer above its rated capacity.
6-4. Verification after operation starts
Verify the following after starting operation:
a) There is no abnormal noise, vibration, or overheating.
b) There is no shock or overload.
c) The temperature is not unusually high.
Note) The reducer may generate heat during the first two or three days of operation. This is expected and is not a problem.
However, if the housing temperature exceeds 100°C, it could indicate an undersized reducer, low oil level, or improper
installation, so inspect these as necessary. To prevent burn injuries, do not touch the reducer with your bare hands.

[ 7 ] Maintenance
Danger
Never touch the shaft or other rotating parts when maintaining or inspecting the reducer during operation. Catching and personal injury can occur.
When performing inspection inside the product while stopped, be sure to stop rotation of the drive and driven equipment and allow the inside to
sufficiently cool before inspecting while continually ventilating the inside. Also, during inspection, have safety check personnel positioned outside,
and continually check the safety with the operator. Carefully check whether the inside is slippery due to lubrication oil, and take full safety
measures. Otherwise, physical injury can occur.
Caution
(Daily inspection and maintenance)
Follow the instruction manual for replacing the lubrication oil and grease. Be sure to use the oil type recommended by the manufacturer.
Otherwise, equipment damage can occur.
Do not touch the surface of the reducer with a bare hand, as it can be very hot. Burns can occur.
Do not replace the lubrication oil during operation or immediately after stopping operation. Burns can occur.
If a problem occurs, diagnose the problem according to the instruction manual. Never operate the reducer until the source of the problem is
determined and corrective measures have been taken.
7-1. Maintenance precautions
・
・
・
・
・
During maintenance, wear appropriate clothing for the task and appropriate safety gear (safety glasses, gloves, safety shoes, etc.).
Make sure your surroundings are safe so as not to create secondary damage.
Be sure to turn off the power, and check that the machine has come to a complete stop. Avoid accidentally turning on the power.
The reducer becomes hot during operation, so be careful not to directly touch it, as burns can occur.
Follow Part II, Chapter I, Section 1, "General Standards" of the Ordinance on Industrial Safety and Health.
7-2. Daily inspection
Use the necessary measuring equipment to perform daily inspections according to the following procedures, while paying attention to
the operation status. Failure to perform daily inspections can result in equipment problems.
Inspection items
Inspection details
Noise
Is the noise louder than usual? Are there any unusual noises?
Vibration
Is there any unusual vibration? Any rapid changes in vibration?
Temperature
Is the surface temperature of the reducer higher than usual? Any rapid temperature rises?
Oil level
Is the oil level correct when the machine is stopped?
Mounting bolts
Are any of the bolts loose?
Chain/belt
Are the chains/belts loose?
Lubricant condition
Has the lubricant blackened due to abrasion powder?
Oil leakage
Are there any leakages from the connection points on the reducer, oil seals, caps?
Pressure vent
Are the holes for air bleeding clogged?
Note) If a problem occurs, immediately stop operation and perform a detailed inspection.
Note) Contact your distributor if the cause cannot be determined or repair is not possible.
7-3. Inspection and replacement of the oil seal
・Oil seals wear and have expected lifetimes, which may eventually lead to oil leakage. Lifetimes may be shorter when used at high
temperatures, high rotating speeds, outdoors, or otherwise harsh conditions. Inspect the oil seal at regular intervals, and replace
immediately if oil leaks exist. Always replace oil seals with the same model number and material. (Do not use oil seals made of different
materials as this can cause oil leakage.) Refer to the oil seal manufacturer's catalog when replacing. The procedures for replacing the oil
seal and filter are described on the following page.
・Occasionally, during the early days of operation, grease filled during the assembly process may seep out of the oil seal lip. This is
normal and does not affect the performance of the reducer.

Item
Replacing the oil seal
and filter
Protection from the shaft
● Before press fitting the oil seal to the lids (seal support, output
bearing support, motor flange), insert the oil seal press fitting part
for the filter and shim in that order. (If there is a housing, remove it
using the same order.)
● Before press fitting the oil seal, be sure to fill the oil seal lip groove
with a mineral-based lithium grease. (About 50% of the lip space)
● Coat the outside of the oil seal with a liquid gasket. (You can skip
this if the outside of the oil seal is rubber.)
● Press fit the oil seal using a flat press fitting jig, as shown in the
drawing, so the oil seal is not at an angle. Also see the catalog of
the oil seal manufacturer for information on installing the oil seal.
Installing the
seal support
Replacing the oil seal
Removing the filter
● Remove the lids (seal support, output bearing support, motor
flange).
● Using the groove for removing the oil seal inside the lid, remove
the old oil seal. Also
remove the filter and shim
at this time.
● Completely remove the
liquid gasket attached to
the lid, reducer housing,
and polyester shim.
● If there is a housing,
remove it using the same
order as that for the lids.
Installing the oil seal
and filter
● Be sure to check that lubrication oil is being drained inside the
reducer before removing the housing and lids (seal support,
output bearing support, motor flange).
● If the lids (seal support, output bearing support, motor flange) are
removed while there is a load on the shaft, the shaft can move,
resulting in injury, so check that there is no load on the shaft.

Remove the reducer from the device. Remove all parts installed in
the input and output shafts of the reducer. Provide sufficient
maintenance space to enable safe work. Stabilize the reducer before
performing maintenance. Removing the lids (seal support, output
bearing support, or motor flange) while still mounted to the device
can cause the shaft or other internal parts to fall or pop off due to the
mounted position.

・Procedures for replacing oil seals and filters
Use the following procedures to replace oil seals and filters installed in the lids, such as the housing, input seal support, output seal support,
output bearing support, and motor flange. Check the model number and dimensions in the catalogs or instruction manual to verify that the
oil seal or filter for replacement is correct. You cannot use an oil seal or filter with a different model number or dimensions. Contact us for the
replacement filter.
Note) Defects resulting from customer replacement of the oil seal are not covered under the warranty.

Oil seal
Coat with liquid gasket
● Coat the mating parts of the lids (seal support, output bearing
support, motor flange) with a liquid gasket. (See the above
diagram.)
● When the lids (seal support, output bearing support, motor
flange) are assembled to the reducer housing, the stepped
section of the shaft can damage the oil seal lip. Wrap with vinyl
tape before assembling, and then remove the vinyl tape after
assembly is completed.
(Be careful as the keyway of the shaft can also damage the lip
in the same way.) Use the same procedure for the housing.
Vinyl tape
● Install the lids (seal support, output bearing support, motor
flange) to the reducer housing. Also install the polyester shim at
this time.
● Install the bolts and tighten to the specified torque.
If the liquid gasket is not coated well when installing the lids (seal
support, output bearing support, motor flange), oil can leak from
the area where the reducer housing and lid meet.
About 24 hours after replacing the oil seal, check for oil leaks from
the mating surface. If an oil leak does occur, remove the lids again,
peel off the liquid gasket, and apply it again.

8-1-7. Operation
(1) Pre-start inspection
After completing installation and wiring, inspect the following items before turning on the switch:
an appropriately sized earth leakage breaker and overcurrent relay is wired into the motor circuitry.
all wiring is correct.
the motor is properly ground.
Make sure the equipment incorporates failsafe measures to prevent accidents from occurring during operation of the reducer, or in
the event the reducer stops working properly.
(2) Voltage or frequency fluctuation
If the voltage or frequency applied to the motor is not the specified value, be careful as the characteristics will change. The motor
voltage can fluctuate within ±10% of the rated voltage.
(3) Load
Loading the motor above the rated capacity can affect its life and result in damage. Be sure that the rated amperage listed on the
motor nameplate is not exceeded.

(4) Verification after operation starts
Verify the following after starting operation:
a. the direction of rotation is correct.
b. the maximum current is within the value listed on the nameplate.
c. there is no abnormal vibration or noise.
d. the start frequency is not high.
e. there is no shock.
f. the temperature is not unusually high.
28
8-1-8. Variable frequency operation
(1) Using a variable frequency drive (VFD) (using a variable frequency drive (V/F control) for a standard motor)
1) Usable frequency range
The usable frequency range is 120 Hz max. Use within the VFD's allowable frequency range when operating at low frequency
(low speed range).
2) Torque characteristics
Refer to the graph below for frequency and torque characteristics.
• Torque is inversely proportional to rotating speed. Therefore, in the high speed range, the kW becomes constant and causes
the torque to drop.
As the speed increases, so does the vibration and operating noise of the motor, fan, and reducer.
• In mid speed ranges, the motor delivers basically the rated torque.
• In low speed ranges, temperature rise becomes noticeable as the duty cycle and cooling efficiency drop.
To prevent these effects from occurring, the motor should be controlled to deliver less torque as shown in the graph below.

continuously
Output torque (%)

Output torque (%) is 100% when motor runs at 60 Hz rating.
(Set base frequency to 60 Hz)
Note) Torque characteristics shown here only for the motor itself. For practical use, the efficiencies of the reducer must be
taken into consideration.
3) When used with a brake
• The brake must be supplied with the rated frequency and voltage at all times. When using a VFD, always wire the brake for
separate control by referring to the wiring diagram on pages 26 and 27.
For standard motors, the brake leads are factory connected to the motor leads under the same terminal screw. Remove the
screws and wire separately.
• Apply brakes at 60 Hz (1800 r/min) or less.
Braking at high speed ranges above 60 Hz may cause mechanical damage or abnormal abrasion wear on the brake linings.
Always apply at 60 Hz or less.
• Low speed operation also lowers the motor's cooling capacity which can reduce the life of the motor in terms of thermal
resistance. In this case, reduce the duty of the brake under power.
4) Notes
• When operating at low frequencies or above 60 Hz, reduce the torque as shown in the graph above.
• When using an VFD with a 400 V class motor, high voltage spikes occur as the VFD switches (micro surge), which can result
in insulation failure. Because the motor must be protected against micro surges, TEM provides protection against micro
surges for all standard 400 V class motors, even if not instructed to do so.
• Temperature rise, noise, and vibration levels will be higher than when using mains service power.
• To protect the motor from overheating, set the VFD's electronic thermal protector for general-purpose motor characteristics, or
install a thermal relay between the VFD and motor.
• When using the motor at the base frequency of 50 Hz, set the output torque to 0.8x the value in the table above.
• The motor may resonate depending on the rotating speed and frequency. When running the motor continuously, avoid the
resonance frequency by changing the VFD's carrier frequency.
• When test running under light loads, the motor may draw a large current at low frequencies.
This is a characteristic of the motor and is not abnormal. The current can be lowered by changing the settings in the VFD
(lowering the torque boost and/or the V/F ratio, and using torque vector control).
• Continuous operation at frequencies above 60 Hz will cause the reducer to heat up and should thus be avoided. Contact us
for details.

The usable frequency range is 120 Hz max. Use within the
Max torque when run continuously
VFD's allowable frequency range when operating at low
frequency (low speed range).
2) Torque characteristics
Refer to the graph on the right for frequency and torque
characteristics.
These motors deliver constant torque from 6 to 60 Hz, with
the continuous operating torque at 60 Hz. Note, on 2.2 kW
and 3.7 kW motors, the torque drops at 10 Hz or less.
3) When used with a brake
The brake must be supplied with the rated frequency and
Output frequency (Hz)
voltage at all times. When using a VFD, always wire the

brake for separate control by referring to the wiring diagram
on pages 31 and 32.
Note) Torque characteristics shown here only for the motor itself. For practical
use, the efficiencies of the reducer must be taken into consideration.
4) Notes
• From 60 to 120 Hz, VFD motors enter their rated horsepower range as do standard motors. The output torque is limited in this
range so be careful of the load torque.
• The input voltage from the VFD to the motor should be set by adjusting the base frequency and base voltage settings in the
VFD. Make sure the VFD's output voltage falls within the voltage and frequency specifications on the motor nameplate. (When
using a VFD motor, the base frequency must be set to 60 Hz.)
VFD motors should not be connected directly to the source without going through the inverter. Otherwise, voltage fluctuations
can cause frequent amperage increases. (This is not a problem for brief operation such as for test running and emergency
use.) This effect is particularly noticeable at 50 Hz.
• Always set the base frequency of the VFD to 60 Hz.
• If 100% torque is required at slow frequency ranges, apply the torque boost feature in the VFD. Excessive torque boost over
prolonged continuous operation can cause overheating and should be avoided.
• Also refer to the notes on variable frequency driven motors on page 29.

8-2-3. Manual release procedure
Remove the fan cover , insert the screw or hex cap bolt (effective length of 10 to 15 mm) that applies to the table below from the 2
holes for manual release ⑳, and screw them in. Once it becomes difficult to rotate the screw, at approximately 1/3 or 1/2 turn, the brake
gap becomes almost 0 and is released.
Models with a 0.2 to 2.2 kW motor have a fan ⑪, and if the holes for manual release are hidden on the fan, screw in 1 screw, gently
turn the fan by hand with the brake slightly released, move the position of the fan, and screw in the other screw. After servicing, make
sure to loosen the screws, remove them from the brake unit, and replace the fan cover before operating the motor.
Operating with the brake released can cause accidents. Never loosen the U nut and manually release the brake.

loosening and tightening of the U nuts can cause them to break
or reduce the threadlock effect.)
c. Confirm that AC power is supplied to the brake motor, and that
the motor is rotating properly without coming into contact with
the armature and brake pad. If there is contact, adjust the gap
so that it is a little bit larger.

Caution: When rotating the U nut, insert a hex bolt wrench into the hex socket hole of the guide bolt and secure it so that it does
not rotate before rotating the U nut. Rotating both together can cause the guide bolt to loosen. If the U nut has been
removed or repeatedly loosened and tightened, replace it with a new U nut. (For SLB01 to SLB07, use size M5 x P0.8,
and for SLB15/SLB22, use M8 x P1.25.) At this time, thoroughly degrease the U nut and coat it with a threadlocker. Do
not disassemble the brake parts, as this can cause abnormal operation of the brake parts if they cannot be
re-assembled or if assembled incorrectly.

[ 9 ] Handling a Semi-standard Package
9-1. Handling POWER-LOCK specifications
(1) Mounting procedures
*These procedures outline the standard torque arm mounting for a POWER-LOCK.
● The POWER-LOCK is shipped temporarily fixed to the output shaft. After removing it from the reducer, mount it on the
machine/equipment using the procedures below.
● These procedures are for standard installation (mount the POWER-LOCK on the counter flange face side, position the flange
toward the machine/equipment side, and mount the POWER-LOCK to the end of the driven shaft).
● Recommended tolerance for driven shaft diameter: h6
1） Make sure there are no scratches or dust on the periphery of the driven shaft (recommended tolerance: h6), and the inside of
the hollow output shaft of the reducer. Using the lifting bolt on the top surface of the reducer, suspend the reducer and insert it
into the driven shaft.
2） Thoroughly clean all dust and oil from the periphery of the output shaft of the reducer and inner shaft of the POWER-LOCK
with a rag. Lightly push the POWER-LOCK onto the periphery of the reducer output shaft.
Note) If the POWER-LOCK is too heavy, disassemble it and reassemble it on the output shaft.
Note) The bolts and main unit of the POWER-LOCK SL Series are coated with a special lubricant and require no further
lubrication.
3） After inserting to the prescribed position, determine the relative positions (circumferential and axial) of the driven shaft and
reducer output shaft. Once the position has been determined, use a torque wrench to lightly tighten the roughly diagonal
tightening bolts (In Fig. 2, work from bolt (1) → bolt (5)).
Note) 1/4 fastening torque (refer to Table 9-1 on page 37) is ideal.
Torque wrench
Figure 1 Mounting
Figure 2 Bolt tightening sequence
36
4） After the positioning is fixed, tighten the other bolts in sequence.
Note) As in (3) above, tighten the bolts to approximately 1/4 fastening torque.
Note) When tightening, work clockwise from the first bolt. Tighten each bolt no more than 30° each.
(In Figure 2, repeat (1) → (2) → (3) → (4) → (5) → (6) → (7) → (8) → (1))
5） Continue tightening in the same sequence as in Step 3, this time increasing the torque to 1/2 (refer to Table 9-1).
6） Continue tightening in the same sequence as in Step 3, this time using the prescribed torque (refer to Table 9-1).
7） Finally, tighten all tightening bolts clockwise in sequence with the specified torque. Repeat this several times. This completes
the installation.
(2) Removal
*These procedures outline the standard torque arm mounting for a POWER-LOCK.
Note) Make sure power to the machine and equipment is turned off when removing.
Note) If the bolts in the POWER-LOCK are loosened carelessly, the POWER-LOCK may suddenly release and pop off. This
will also free the reducer and put it in an unbalanced state where it could turn and be very dangerous. Always verify the
following points:
● Make sure there is no torque or thrust load on the output shaft of the reducer. Make sure to remove any loads attached.
● If the weight of the reducer and the POWER-LOCK is heavy, place them in a stable condition. (The lifting bolt on the reducer
can be used for this.)
Note) Forcibly removing the POWER-LOCK can leave scratches on the shaft and render it unusable, so take precautions. If
rust exists, remove it with a commercially available rust removal spray. Make sure to follow the above directions before
performing the procedures below.
1） Loosen the POWER-LOCK tightening bolts in sequence. As mentioned in the notes, do not completely remove the bolts at
once. Loosen each tightening bolt head by about 30°.
2） After confirming that the POWER-LOCK has fully released, suspend the reducer by its lifting bolt and remove it from the
driven shaft.
(3) General notes
1） Always use a torque wrench to tighten the tightening bolts. Failure to use a torque wrench with an adjustable dial is
inaccurate and can cause problems. Also note that using a pipe as a lever gives inaccurate tightening torque and should
never be done.
2） Do not use any bolts other than those supplied with this product. In case of damage or loss, contact your TEM dealer for
replacement or new bolts.
(4) Reusability
● If reusing the removed POWER-LOCK, thoroughly remove any dirt from it with a rag. The bolts and main unit of the
POWER-LOCK/SL Series are coated with a special lubricant. If you notice the coating is peeling off, coat it with molybdenum
anti-friction grease (Molycoat, etc.) prior to reuse.
(5) Ambient conditions
● The POWER-LOCK SL Series can be used outdoors in an ambient temperature range of -30°C to +200°C. However, in this
case the POWER-LOCK is considered part of the reducer which limits it to the ambient conditions of the reducer motor. Use the
POWER-LOCK in accordance with "Installation" in section 3, in page 11.

(1) Mounting procedures
These procedures outline the standard torque arm mounting.
● The taper bush is shipped temporarily fixed to the output shaft. After removing it from the reducer, mount it on the
machine/equipment using the procedures below.
● These procedures are for standard installation (mount the taper bush on the flange face side, position the flange toward the
machine/equipment side, and mount the taper bush between the machine/equipment and reducer).
● Recommended tolerance for driven shaft diameter: g7
1. Taper bush Type I
1） Make sure there are no marks or dust on the outer periphery of the driven shaft, and install the key prepared by the customer.
Note) Only the Type II driven shaft key is shipped with the reducer.
2） Thoroughly clean all dust and oil from the inner and outer peripheries of the taper bush with a rag. Then line up the driven shaft
key and insert the taper bush. Once inserted, install the provided key in the keyway on the outer periphery of the taper bush.
Note) Do not coat the taper bush with any oil.
3） Thoroughly clean all oil and dust from the inner periphery of the hollow output shaft on the reducer with a rag. Then suspend
the reducer by its lifting bolt and lineup the keyway as in Step 2 and insert it into the taper bush.
Note) SWJ50 to 63: No lifting bolts provided. Move by hand.
4） Verify that the reducer is installed in the correct position with respect to the machine/equipment. Align the tightening bolt to the
threads on the flange of the taper bush and tighten.
Note) Use a torque wrench set to the torque outlined in Table 9-2 on page 39 to accurately tighten the bolts.
5） After tightening the bolts, verify that the end face of the hollow output shaft is not interfering with the taper bush.
Note) If the end face of the hollow output shaft is interfering, either the shaft diameter of the driven shaft is too small or the
tightening bolts are not tightened evenly.
2. Taper bush Type II
For Type II, the driven shaft key doubles as the hollow output shaft key. Therefore, the basic procedure is the same as for Type I
except that the supplied key is used.

(2) Removal
These procedures outline the standard torque arm mounting.
Note) Make sure power to the machine and equipment is turned off when removing.
Note) If the tightening bolts in the taper bush are loosened carelessly, the taper bush may suddenly unlock and free the
reducer, putting it in an unbalanced state where it could turn and be very dangerous. Always verify the following points:
● Make sure there is no torque or thrust load on the taper bush and/or the reducer.
● If the weight of the reducer is heavy, place it in a stable condition. (The lifting bolt on the reducer can be used for this.)
Note) Verify that the tightening bolts do not have any rust on them. Attempting to forcibly remove rusty tightening bolts can
damage the threads and make it impossible to remove. Additionally, the bolts cannot be reused. If rust exists, remove it
with a commercially available rust removal spray.
Make sure to follow the above directions before performing the procedures below.
38
1） Suspend the reducer using the lifting bolt on the top surface of the reducer.
2） Loosen the taper bush tightening bolts in sequence.
Note) As mentioned in the notes, do not completely remove the bolts at once. Loosen each tightening bolt head by 30°.
3） Take the removed bolts and insert them into the two draw holes in the bush. Tighten the bolts, which will push out the taper
bush and release the lock.
4） After completely releasing the taper bush, remove the reducer from the driven shaft.
(3) Flange mounting
● A torque arm mounting is assumed for mounting and fixing a taper bush because there should be no thrust load on the driven
shaft and the reducer's bearings.
● If using the taper bush type for flange mounting, follow the procedures below and make sure there is no thrust load on the driven
shaft and the reducer's bearings.
1） Make the driven shaft free in the thrust direction.
2） Insert the taper bush into the driven shaft, then insert and fix the reducer.
3） Fix the driven shaft so that it receives no thrust.
(4) General notes
1） Always use a torque wrench to tighten the tightening bolts. Failure to use a torque wrench with an adjustable dial is inaccurate
and can cause problems. Also note that using a pipe as a lever gives inaccurate tightening torque and should never be done.
2） Do not use any bolts other than those supplied with this product. In case of damage or loss, contact your TEM dealer for
replacement or new bolts.
3） The taper bush tightening bolts are also used as draw bolts during removal. Provide enough room to remove the bolts by
referring to the detailed dimensions (bolt lengths and PCD) in the catalog.
(5) Reusability
● If reusing the removed taper bush, thoroughly remove any dirt from it with a rag.
(6) Ambient conditions
● The taper bush specifications are considered part of the reducer, which limits the specifications to the ambient conditions of the
reducer motor. Use the taper bush in accordance with "Installation" in section 3 in page 11.
