Material loss in bearings is considered to come primarily from abrasive wear, adhesive wear, and contact fatigue wear. Within a properly operating rolling-element bearing, the main wear mechanism is rolling-contact fatigue. In the absence of gross sliding, the subsurface stresses govern the initiation of severe fatigue wear (spalling). Often-cited criteria include maximum orthogonal shear stress, octahedral shear stress, and von Mises stress, all of which are typically subsurface.
