Rolling bearing is the operation of the rolling element bearing and sliding friction into rolling friction between shaft seat, thereby reducing friction loss of a precision mechanical components. Rolling bearings generally consists of inner ring and outer ring, rolling body and keep the frame of four parts, the function of inner ring is match with shaft and shaft rotation; Outer ring is used to match the bearing seat, a support role.
Rolling body is with the aid of maintains a uniform distribution of the rolling element between inner ring and outer ring, its shape size and quantity directly affects the using performance and life of rolling bearing; Maintains a uniform distribution can make the roller, prevent fall off, roller guide roller rotation lubrication.
