Bearing Analysis: Peeling
Condition
Peeling is a cluster of very small spalls (size about 10µm). Peeling can also include very small cracks which develop into spalls
Cause
Likely to occur in roller bearings. Tends to occur if surface of opposite part is rough or lubrication characteristics are poor. Peeling may develop into flaking
Solution
- Control of surface roughness and dust
- Selection of appropriate lubricant
- Proper break-in
