Bearing Spalling


Damage mode Causes Solutions

49棋牌app ● 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

Bearing Spalling


● inner ring of radial ball bearing
● spalling caused at the slope with the roller path
● caused by misalignment during installation

Bearing Spalling

● ball surface spalling
● caused by impact load while stalling

Bearing Spalling

● spherical roller bearing inner ring
● spalling appears only at roller path surface of one row
● damage due to poor lubrication
