Welcome!
A motor cannot work without bearings. "Because the shaft can move in any direction, the motor requires that the shaft only rotate when it is operating.". Theoretically, it is impossible to achieve the transmission effect. Moreover, bearings can also affect the transmission. In order to reduce this impact, good lubrication must be achieved on the bearings of high-speed shafts. Some bearings already have lubrication, called pre lubricated bearings, while most bearings must have lubricating oil. During high-speed operation, friction not only increases energy consumption, but also makes it easy to damage the bearings. The idea of converting sliding friction into rolling friction is one-sided, because there is something called sliding bearings.
In terms of its function, it should be support, which is literally used to support the shaft, but this is only part of its function. The essence of support is to be able to bear radial loads. It can also be understood as being used to fix the shaft. The automatic selection of bearing quick, easy and excellent is included. It is to fix the shaft so that it can only rotate and control its axial and radial movement.
