Why did my Bearing Fail? Common Failures FAQ | Damage Photographs - JAD Analysis

Bearing Flaking or Surface Fatigue. Flaking due to rolling fatigue occurs when small pieces of bearing material are lifted and broken off the smooth surface of the raceway or the rolling elements. This flaking causes regions with a rough and coarse texture. Fatigue damage in a loaded zone of a tapered roller bearing inner ring Flaking on the

Tapered Roller Bearing Damage Detection Using Decision Fusion Analysis …

Failure progression tests were performed with tapered roller bearings under simulated engine load conditions. Tests were performed on one healthy bearing and three pre-damaged bearings. During each test, data from an on-line, in-line, inductance type oil debris sensor and three accelerometers were monitored and recorded for the occurrence of bearing failure.
