Assessing the rolling bearings

To assess the rolling bearings, it is generally not necessary to dismantle the machines. The
motor only has to be dismantled if the bearings are to be replaced.
The state of a rolling bearing can be assessed by analyzing the bearing vibration. The
measured values provide an indication and can be assessed by specialists. In this case, please
contact the Service Center.

Explosion hazard due to overheating of the roller bearings
If the roller bearings are not regularly regreased, local overheating may be possible, and, as
a consequence, an explosion in an explosive atmosphere. This can result in death, serious
injury, or material damage.
● Regrease the roller bearings regularly according to the lubrication plate.
● Implement bearing temperature monitoring if not yet in existence.
