Fatigue failure is related to the stress the bearing is subjected to over time. Fatigue failures in bearings typically originate sub-surface and eventually will propagate to the surface, and in time, will appear in what is referred to as a spall (see Figure 1). Fatigue failure is, in part, interrelated to the purity and the quality of the steel.
