[0002] Bearing (Bearing) is an important spare part in contemporary mechanical equipment. Its main function is to support mechanical rotating body, reduce its friction coefficient in the movement process, and ensure its rotation accuracy. According to the different friction properties of moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. Compared with sliding bearings, the radial dimension, vibration and noise of rolling bearings are larger, and the price is also higher. Rolling bearings are generally composed of outer ring, inner ring, rolling body and retainer. According to the shape of the rolling body, the rolling bearing is divided into two categories: ball bearing and roller bearing. Bearing ("Bearing", Japanese people call "axle accept") is a component that fixes and reduces the friction coefficient of load in the process of mechanical transmission.
