Bearing fast and easy automatic selection is included. Is to fix the shaft so that it can only achieve rotation, and control its axial and radial movement. The motor can't work without bearings. Because the shaft may move in any direction, the shaft can only be rotated when the motor is working. Theoretically speaking, it is impossible to realize the function of transmission. Not only that, the bearing will also affect the transmission. In order to reduce this influence, good lubrication must be realized on the bearing of the high-speed shaft. Some bearings already have lubrication, which is called pre-lubricated bearings. Most bearings must have lubricating oil, which is responsible for not only increasing energy consumption but also easily damaging the bearings due to friction during high-speed operation. The idea of turning sliding friction into rolling friction is one-sided, because there is something called a sliding bearing.
