ible to mix different types of grease.
Prolonged storage periods reduce the useful lifetime of the bearing grease. Check the
condition of the grease if the equipment has been in storage for more than 12 months. If the
grease is found to have lost oil content or to be contaminated, the machine must be
immediately relubricated before commissioning. For information on permanently-greased
bearings, please refer to the section titled Rolling bearings (Page 106).
Procedure
To relubricate the rolling bearings, proceed as follows:
1. Clean the grease nipples at the drive end and non-drive end.
2. Press-in the specified grease and amount of grease according to the data stamped on the
lubrication plate.
– Please observe the information on the rating and lubricant plates.
– Regreasing should be carried out when the motor is running (max. 3600 rpm).
