Caution
When re-lubricating the bearings, the grease drain screws on the DE side and
NDE side bearing plate, where present, must always be opened!
Cleaning intervals
The regular removal of old grease is necessary in order not to negatively affect
the expected service life of the bearings.
Note
It must be ensured that the running tracks of the bearing and the rolling
elements are not damaged during the cleaning process. Do not use metal
tools as aids. Make sure there is no dust or dirt near the rolling element
or in the rolling element!
This causes a drastic shortening in service life!

4.3 Repair
Spare parts lists and regular drawings do not contain the types and dimensions of the parts.
Therefore, the type and dimensions of the concerned parts should be determined during disassembly
and they should be marked for assembly.
4.3.1 Joint sealing
For motors with protection class IP56 or higher (see rating plate), the part joints between the motor
housing and the bearing plates should be sealed with a suitable, non-hardening sealing mass.
5 Spare parts
For spare parts orders, the motor type and motor number (details can be found on the rating plate)
must always be specified in addition to the exact part designation.
With the exception of standardised commercially available and equivalent parts, e.g. ball bearings,
only original parts may be used.
This applies in particular for seals and terminals.
6 Final decommissioning (disassembly, recycling,
disposal)
Always disassemble motors in such a way that environmentally-friendly recycling and disposal of the
motor components is possible.
When recycling and disposing of the disassembled motor components, always observe the legal
regulations and provisions applicable at the time of the final decommissioning!
