Bearing Failure Modes: Recognition and Analysis
Understanding bearing failure modes enables root cause analysis. Pattern recognition guides corrective action and prevents recurrence.
Fatigue Spalling
Spalling appears as flaking on raceway surfaces. It results from repeated stress cycling. This is a normal failure mode approaching design life.
Abrasive Wear
Contamination causes abrasive wear. Particles embed in bearing surfaces and roll through the load zone. Clean environments minimize this wear mode.
Corrosion
Moisture and contaminants cause corrosion. Rust pits create stress concentrations leading to early failure. Proper storage and sealing prevent corrosion.
Installation Damage
Impact damage, improper fits, and misalignment cause immediate or rapid failure. Careful installation prevents this category of failures.
