The role of bearings

Bearings are an important part of contemporary machinery and equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and guarantee its rotation accuracy.
In terms of its role, it should be supportive, that is, the literal interpretation is used to support the axis, but this is only part of its role, and its support is to be able to bear the radial load. It can also be understood that it is used to fix the shaft. Bearing quick and easy excellent automatic selection is included. It is the fixed shaft that allows it to rotate only and control its axial and radial movement. Motors do not work at all if they do not have bearings. Because the shaft may move in any direction, the motor requires the shaft 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 the impact of high-speed shaft bearings must achieve good lubrication, and some bearings already have lubrication, called pre-lubricated bearings, and Most bearings must have lubricating oil, responsible for high-speed operation, because friction will not only increase energy consumption, but more terrible is that it is easy to damage the bearing. The argument for turning sliding friction into rolling friction is one-sided because there is something called a sliding bearing.
