Bearing Spalling: A Critical Issue Threatening Industrial Equipment
Bearing Spalling: A Critical Issue Threatening Industrial Equipment
Bearing spalling, a common form of bearing failure, poses a significant challenge to industries worldwide. It occurs when small pieces of material break away from the raceways or rolling elements of a bearing, leading to severe consequences. According to NTN Bearing Corporation, approximately 14% of bearing failures are attributed to spalling.
Story 1: The Impact of Bearing Spalling
Benefit: Reduced downtime and production losses
How to:
- Implement regular bearing inspections to detect early signs of spalling.
- Use condition monitoring systems to monitor bearing vibrations and temperatures.
- Replace bearings before they fail completely to prevent catastrophic damage.

Story 3: Diagnosing Bearing Spalling
Benefit: Early detection and proactive maintenance
How to:
- Inspect bearings for visual signs of spalling, such as pitting or flaking.
- Listen for unusual noises coming from bearings, indicating spalling or other damage.
- Use vibration analysis tools to identify excessive vibrations caused by spalling.
