Operating situations and characteristics can vary widely. For this reason, only general
maintenance intervals are specified here. Maintenance intervals should therefore be scheduled
to suit the local conditions (dirt, starting frequency, load, etc.).
Table 9-3 Operating period intervals
Measures Operating period intervals Intervals
Initial inspection After 500 operating hours After 1/2 year at the latest
Relubrication (optional) See the lubricant plate
Clean Depending on the degree of pollution
Main inspection Approximately every 16000 operating
hours After two years at the latest
Drain condensate Depending on the climatic conditions
9.6.7 Re-greasing
For machines with regreasing system, relubrication intervals, grease quantity and grease grade
are provided on the lubricant plate. Additional data can be taken from the main machine rating
plate.
Grade of grease for standard motors (IP55) UNIREX N3 - ESSO.
Note
It is not permissible 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 100).
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).
