May 16, 2020 In the grinding process of the bearing, its working surface is ground by the high-speed rotating grinding wheel, so if the grinding does not follow the operating instructions and adjust the equipment, there will be a variety of defects on the bearing working surface, which will affect the overall quality of the bearing.
Nov 23, 2017 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.
