2022-07-14
-
How:
- Contact area between bearing raceway and rolling elements surface is quite small. If an impact force was applied to the bearing, certain indentations will occur and bearing noise shall be observed accordingly.
-
Indentations resulting from impact on bearing raceway and rolling elements surface:
Indentations on bearing raceway and rolling elements surface
Roundness measurement on bearing inner ring raceway
-
Countermeasures:
- 1. Prevent bearings from dropping.
- 2. Prevent bearings from impact either preservation or operation.
