Ermüdungsverschleiß


Ermüdungsverschleiß
Bearing surfaces are subjected to fatigue failures as a result of repeated stressing caused by clearance size particles trapped by the two moving surfaces. At first, the surfaces are dented and cracking is initiated. These cracks spread after repeated stressing by the bearing load, even without additional particulate damage. Eventually the surface fails, producing a spall. Contamination reduces bearing life significantly through fatigue, abrasion and roughening of operating surfaces.
