Bearing (bearing) is a component that fixes and reduces the friction coefficient of load during mechanical transmission. It can also be said that when other mechanical parts move relative to each other on the shaft, they are used to reduce the coefficient of friction during power transmission and keep the shaft center position fixed. In terms of its function, it should be support, that is, it is used to support the shaft literally, 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 it is used to fix the shaft. It is to fix the shaft so that it can only achieve rotation, while controlling its axial and radial movement. The consequence of the motor without bearings is that it cannot work at all. Because the shaft may move in any direction, and the motor is required to only rotate when it is working. Theoretically speaking, it is impossible to achieve the role of transmission. Not only that, the bearing will also affect the transmission. In order to reduce this impact, good lubrication must be achieved on the bearings of the high-speed shaft. Some bearings themselves are already lubricated, which are called pre-lubricated bearings. Most bearings must have lubricating oil. When the load is running at high speed, friction will not only increase energy consumption, but more terribly, it is easy to damage the bearings. The idea of turning sliding friction into rolling friction is one-sided, because there is something called a sliding bearing.
