| 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. |
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. |
- 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
