Bearing Spalling
| Damage mode | Causes | Solutions |
|---|---|---|
|
● fish scale flaking on the raceways or rollers due to fatigue during bearing operation |
● overload, improper installation, load moment ● intrusion of foreign particles, water entering ● poor lubrication, inappropriate lubricant ● inappropriate bearing clearance ● poor precision of housing, uneven rigidity of housing, shaft has large axial deflection ● rusting, etching pit, scratching and brinelling ● brinelling propagation |
● check the load on the selected bearing ● improve installation method ● improve seal device, antirust while machine halt ● use lubricant with adequate viscosity, improve lubrication method ● check the shaft and housing precision ● check clearance |
|
● inner ring of radial ball bearing ● spalling caused at the slope with the roller path ● caused by misalignment during installation |
● caused by impact load while stalling |
● spalling appears only at roller path surface of one row ● damage due to poor lubrication |
