Fitting surfaces are glazed or matted, and sometimes spalled as well. |
Fitting of inner ring is loose on inner ring drive bearing, and that of the outer ring is loose on outer ring drive bearing. If the housing is made of a light alloy such as aluminum, fit may become loose due to the difference of thermal expansion. |
1. Improvement in fit 2. Improvement in machining accuracy of shaft and housing |
- Inner ring of deep groove ball bearing
- Bore wall glazed by creep
- Inner ring of tapered roller bearing
- Spalling due to creep at the middle of bore wall
- Inner ring of thrust ball bearing
- Spalling and friction cracking due to creep on bore wall.
- Inner ring of tapered roller bearing
- Spalling and friction cracking on width surface due to creep crack developed into a split reaching bore wall.
