Roller bearing production
Rolling bearing is a precision mechanical element that changes the sliding friction between the running shaft and the shaft seat into rolling friction, thereby reducing the friction loss. The rolling bearing consists of four parts: inner ring, outer ring, rolling body and retaining frame. The outer ring ACTS in coordination with the bearing pedestal and plays a supporting role. The rolling body is distributed evenly between the inner ring and the outer ring by means of keeping the frame. The size and quantity of the rolling body directly influence the service performance and service life of the rolling bearing.
The holder can make the rolling body evenly distributed and guide the rolling body to rotate for lubrication.
