Bearing Analysis: Spalling
Condition
Score accompanying seizing. Mounting score in axial direction. Scores on roller end face and guide rib-cycloidal scores. Scratches in spinning direction on raceway surface and rolling contact surfaces
Cause
Poor mounting and removing practice. Oil film discontinuation on the contact surface due to excessive radial load, foreign object trapping, or excessive pre-load. Slippage or poor lubrication of rolling elements
Solution
- Improvement in mounting and removing procedures
- Improvement in operation conditions
- Correction of pre-load
- Selection of adequate lubricant and lubrication system
- Improvement of sealing efficiency
