Bearing installed backwards causing unloading of angular contact ball bearings
Considerations during assembly
- Directional bearings must be installed in the right direction to function properly.
- For example: Single row angular contact ball bearings can only accommodate axial loads in one direction. If installed backwards, the axial load will be taken on the low shoulder of the inner ring, which damages the bearing, increases heat generated by the bearing and leads to premature bearing failure.
Action to Do
- During mounting/assembly, make sure the axial load is accommodated by the "high" shoulder.
