· Bearing steel is used to make balls, rollers and bearing rings. Bearings are subjected to extreme pressure and friction during operation, so bearing steels are required to have high and uniform hardness and wear resistance, as well as high elastic limits. The requirements for the uniformity of the chemical composition of bearing steel, the ...

· Even when bearings are being used under ideal conditions, failures of bearings are caused by deterioration of the material due to rolling fatigue. Generally, the service life of bearings is expressed either as a period of time or as the total number of rotations before the occurrence of failures in the inner ring, outer ring or rolling element
