Rolling bearing is a kind of precise mechanical element 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 is to distribute the rolling element evenly between inner ring and outer ring by means of cage, and its shape, size and number Quantity directly affects the service performance and life of rolling bearings; cage can make the rolling body evenly distributed and guide the rolling body to rotate to play a lubricating role.

Effect

Supporting the rotating shaft and its parts, and maintaining the normal working position and rotating accuracy of the shaft, rolling bearings are easy to use and maintain, reliable to work, good starting performance, and high bearing capacity at medium speed. Compared with sliding bearings, rolling bearings have larger radial dimension, poor vibration reduction ability, low service life at high speed and larger sound.
