The machines are equipped with permanently lubricated rolling bearings. The machine may
be equipped with a regreasing device.
CAUTION
Skin irritations and eye inammations
Many greases can cause skin irritations and eye inammations.
• Follow all safety instructions of the manufacturer.
Measures, intervals and deadlines
Measures after operating period intervals or deadlines have elapsed:
Operating situations and characteristics can vary widely. For this reason, only general
maintenance intervals are specied 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) Refer to the lubrication plate or the rating
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
9.2.8 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 dierent 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 (Page129).
