Working principle
During rotation of the shaft, a hydrodynamic film of lubricant

is produced beneath the sealing lip, the thickness of which
depends on shaft speed, oil temperature, oil viscosity and
the pressure or radial load exerted by the sealing lip on the
shaft. Due to capillary forces and the surface topography of

the shaft, the fluid being sealed forms a meniscus under the
sealing lip and is prevented from leaking. The fluid, the seal
material, the film thickness, the sealing lip geometry and the
surface topography of the shaft are governing factors in the
realisation of these capillary forces. A used seal having a

SHAFT MATERIALS,
TOLERANCES OF
SEALS AND
HOUSING
The size of the housing where the Oil Seal has to be pressed
in has to meet certain requirements. The housing has to be
rather smooth (finely machined). Nominal tolerances
according to ISO H8.
Roughness
Tolerance Of The Passing
Shaft
Ra ≤ 0.6 µm
h11
Housing
Ra ≤ 6 µm
H8
To simplify the assembly, it is recommended that the
housing is lubricated. The housing should have a finish of
ca. Ra = 6 mm. Oil Seals with a rubber case cannot rust, in
contrast to Oil Seals with metal cases. Moreover, Oil Seals
with a rubber case can seal a lightly damaged housing
much better than metal cased Oils Seals.
To simplify the correct assembly of the Oil Seal, it is
recommended that the housing has a 30° chamfer on the
front side for a minimum length of 1mm. The Oil Seal, when
mounted, has to fall within the limits of this chamfer. For the
assembly depth, there is a tolerance of -0/0,4mm. The Oil
Seals have an interference fit in the housing, which provides
a good press fit, preventing any leakage.

COMMON
MATERIALS
In the standard construction, our Oil Seals are made from oil
and grease resistant rubber based on NBR (Perbunan). This
material has very good running properties and excellent
wear resistance. For high shaft speeds, large radial
tolerances and good chemical resistance a range of other
rubber materials is available.
