Bearing Analysis: Seizing
Condition
Bearing generates heat and is seized up by heat disabling spinning. Discoloration, softening, and welding of raceway surface, rolling contact surfaces, and rib surface
Cause
Dissipation of heat generated by bearing is not enough. Poor lubrication or lubricant improper. Clearance excessively small. Excessive load (or pre-load). Roller skewing and installation error
Solution
- Improve dissipation of heat from bearing
- Selection of suitable lubricant and determination of optimum lubricant feeding rate
- Prevention of misalignment
- improvement in clearance and pre-load
- Improvement in operating conditions
