Bearings can be seen in many places around us, and there are many types of bearings. Among them, the bearing supplier has made a lot of adjustments and improvements, so that the types and quality of bearings have been continuously improved.
In terms of bearing, its function 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. The automatic selection of bearings is included. It is to fix the shaft so that it can only achieve rotation while controlling its axial and radial movement. The motor cannot work at all without bearings. Because the shaft may move in any direction, and when the motor is working, the shaft can only be rotated. Theoretically speaking, it is impossible to achieve the role of transmission. Not only that, but the bearing will also affect the transmission. In order to reduce this effect, good lubrication must be achieved on the bearings of the high-speed shaft. Some bearings are already lubricated, which are called pre-lubricated bearings. Most bearings must have lubricating oil, which is responsible for not only increasing energy consumption due to friction when running at high speeds, but even more frighteningly, 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.
The above is the main function of the bearing.
