Rolling bearing

Rolling bearing is a kind of precise mechanical component that changes the sliding friction between the running shaft and the shaft seat into rolling friction, thereby reducing the friction loss. Rolling bearings are generally composed of inner ring, outer ring, rolling element and cage. The function of inner ring is to cooperate with the shaft and rotate with the shaft; the function of outer ring is to cooperate with the bearing seat and play a supporting role; the rolling element distributes the rolling element between inner ring and outer ring by means of the cage evenly, and its shape, size and quantity directly affect the service performance and life of rolling bearings. The cage can distribute the rollers evenly and guide the rollers to rotate to lubricate.
