Rolling bearing contact fatigue is a material failure/removal from the surfaces of the bearing raceways and/or rolling elements through a crack initiation and propagation mechanism caused by the cyclic stress field generated within a small rolling contact body volume.

One of the predominant modes of failure for rolling element bearings subjected to rolling or rolling/sliding contacts is rolling contact fatigue (RCF). Rolling contact fatigue is the material fatigue phenomenon. This material fatigue is caused by repeated rolling/sliding contacts between the rolling components and raceways. This cyclic stress field below the bearing surface is responsible for the rolling bearing contact fatigue. For example, ball and rolling element bearings experience highly localized cyclic stresses over a small volume while supporting load and allowing relative motion during their...
