Component assignment
When dismantling or assembling the bearing pay attention to the proper arrangement of the
components particularly if the bearing is the same size on the DE side and NDE side, for
example:
● Bearing shield
● Bearings
● Compression springs
● Spacer washers,
● Covers with different centering length, etc.

Service and Support (Page 161)
If roller-contact bearings with an insulated design are installed, use roller bearings of the same
type as spare parts. This will prevent any bearing damage being caused by bearing currents.
9.3.5 Removing and installing the protecting ring
The protecting ring acts as an outer bearing seal. It sits on the shaft outside the bearing end
shield.
Disassembly
● Once the coupling is detached, you can remove the protective ring from the shaft. After it
has been removed, the protective ring will be deformed and must be replaced.
