The bearing is an important part in the modern mechanical equipment. Its main function is to support the mechanical rotator, reduce the friction coefficient in its motion process, and guarantee its gyration precision, and deep groove ball bearing is the most representative antifriction bearing. Compared with other types of bearings with the same size, the bearing has the advantages of small friction coefficient, high limit rotating speed, simple structure, low manufacturing cost, high precision, no need of frequent maintenance, large size range and multiple forms, and is the bearing with the widest application. It mainly bears radial load, also can bear certain axial load. When it is subjected to only radial loads, the contact angle is zero.

The motor cannot work at all without a bearing. Because the shaft may move in any direction, the motor requires only rotation of the shaft when operating. In order to reduce the influence, good lubrication must be realized on the bearings of the high-speed shaft, some bearings are already lubricated and are called pre-lubricated bearings, and most bearings must be provided with lubricating oil, so that the bearings are not only increased in energy consumption due to friction during high-speed operation, but also easily damaged.
