[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Generally, bearings mainly include bearing rings, bearing inner rings, and balls. The balls are set between the bearing rings and the bearing inner rings. When the bearing rings and the bearing inner rings rotate relative to each other, the sliding friction is converted into rolling friction through the balls to reduce the friction coefficient, thereby reducing mechanical wear and energy consumption. Bearing rings are annular parts of radial rolling bearings with one or more raceways, which are processed by lathes.
