Cracks in the raceway ring and rolling elements. Continued use under this condition leads to larger Cracks or Fractures. | - Excessive interference
- Excessive load, shock load
- Progression of Flaking
- Heat generation and Fretting caused by contact between mounting parts and raceway ring
- Heat generation due to Creep
- Poor taper angle of tapered shaft
- Poor cylindricality of shaft
- Interference with bearing chamfer due to a large shaft corner radius
| - Correct the interference
- Check the load conditions
- Improve the mounting method
- Use an appropriate shaft shape
