Surface fatigue is the failure of a material as a result of repeated surface or sub-surface stresses beyond the endurance limit of the material. Figure 2.1 indicates the theoretical mutual Hertzian stresses occurring when a gear and pinion mesh. There are compressive stresses at the surface and unidirectional and bi-directional sub-surface ...

As this continual arcing occurs over time, the surface areas in the bearing race become brittle, and tiny pieces of metal can break off inside the bearing. Eventually, the damaged material works its way between the bearing's balls and races, causing a grinding effect, which can produce micron-sized pitting, called frosting, or washboard-like ...

If these grinding marks are not completely removed by polishing, they will remove the oil film from the surface of the thrust bearing much like multiple windshield wiper blades. A properly finished crankshaft thrust face should only have very fine polishing marks that go around the thrust surface in a circumferential pattern.

Its surface is hardened up to 70 HRC and has high temperature strength of +350°C to +400°C, as well as very high residual compressive stresses to cope in these aggressive conditions. The rolling elements of some bearings can be made of ceramics like silicon nitride Si3N4, however the bearing rings are normally steel-based.
