The Component Sets enable maximum flexibility in design integration and if
required, can be tailored to your application as a specific configuration. Consisting
of just three individual components, they are very lightweight and compact. The
CobaltLine® Series can be used for ambient temperatures between -40 and 90 °C
with a large selection of special lubricants. Due to their positioning accuracy stable
machine characteristics with short cycle times are guaranteed.
