Bearing Analysis: Creeping
Condition
Fitting surfaces are glazed or matted, and sometimes spalled as well.
Cause
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.
Solution
- Improvement in fit
- Improvement in machining accuracy of shaft and housing
