Rolling-contact bearings
The motors have rolling-contact bearing bushes for grease lubrication. Depending on the
version, the motors are permanently lubricated or are equipped with a regreasing device.
Depending on the type of load, a deep-groove ball bearing or a cylindrical-roller bearing is
fitted as a floating bearing on the drive end.
The DE bearing contains built-in compression springs that help to rebalance the axial play of
the external bearing rings.
