How: Incorrect mounting method and mounting tool defect may lead to an overload force between bearing rings and rolling elements. This will cause a certain indentation on bearing raceway and rolling elements surface.
Indentations resulting from misassembling on bearing raceway and rolling elements surface:

- Countermeasures:
- 1. Use appropriate methods for mounting bearings.
- 2. Use appropriate tools as required.
