What is the function of bearings?
Bearing is used to fix and reduce the friction coefficient of load during mechanical transmission. It can also be zhi said that when dao relative motion is generated between other parts on the axis, it is used to reduce the friction coefficient in the process of power transmission and keep the center of the axis fixed. Bearing is one of the most important parts in modern machinery and equipment. Its main function is to support the mechanical rotating body to reduce the friction coefficient of mechanical load in the process of transmission. Bearings can be divided into rolling bearings and sliding bearings according to the friction properties of motion elements
