Bearing Knowledge–Material factors and control affecting bearing life
Material Factors Affecting Bearing Life The early failure modes of rolling bearings are mainly rupture, plastic deformation, wear, corrosion and fatigue, and under normal conditions are mainly contact fatigue. In addition to service conditions, the failure of bearing parts is mainly restricted by the hardness, strength, toughness, wear resistance, corrosion resistance and internal stress state of steel. The main internal factors that affect these performance and state are the following. 1. Martensite in Quenched Steel…
