The textile machine bearing is a component that fixes and reduces the friction coefficient of the load during mechanical transmission. It can also be said that when other mechanisms are relatively moved relative to each other on the shaft, the mechanism for reducing the coefficient of friction during power transmission and maintaining the center position of the shaft is fixed. Bearings are a very important part of contemporary machinery. Its main function is to support the mechanical rotating body to reduce the mechanical load friction coefficient of the equipment during the transmission process. According to the friction properties of moving components, bearings can be divided into two types: rolling bearings and plain bearings.
