The machines are equipped with permanently lubricated rolling bearings. The machine may be
equipped with a regreasing device.
CAUTION
Skin irritations and eye inflammations
Many greases can cause skin irritations and eye inflammations.
● 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 specified here. Maintenance intervals should therefore be
scheduled to suit the local conditions (dirt, starting frequency, load, etc.).

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 90).
