Bearing Analysis: Indentation
Condition
Hollows in raceway surface produced by solid foreign objects trapped or impacts (False brinelling)
Cause
Ingress of solid foreign objects Trapping of flaked particles Impacts due to careless handling
Solution
- Keeping out foreign objects
- Check involved bearing and other bearings for flaking if dents are produced by metal particles
- Filtration of oil
- Improvement in handling and mounting practices
