What is the Use Of Bearings?

To put it simply, the function of the bearing is to play a supporting role. If the transmission part (such as the shaft) is directly matched with the hole, the transmission resistance will be large, and the transmission part will not be easy to replace after having seriously worn. Moreover, the bearing depends on the rolling contact to support the transmission parts, so it has the following characteristics: low sliding resistance, low power consumption, and easy startup, and so on.


The main function of the industrial bearings is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. It can be understood that it is used to fix the shaft so that it can only be rotated, so as to control the axial and radial movement. The bearings can not work without the help of the shaft. Because the shaft may move in any direction, and the shaft can only be rotated while working.


The bearings are widely used in automobiles: rear wheels, transmissions, electrical components. Electrical: general motors, household appliances. Instruments, internal combustion engines, construction machinery, railway vehicles, handling machinery, various industrial machinery. Machine tool spindles, agricultural machinery, high-frequency motors, gas turbines, centrifugal separators, front wheels of small cars, differential pinion shafts, etc., almost as long as they need to rotate, they all use bearings.
