The primary function of a bearing is to provide support for rotating components. If transmission elements, such as shafts, were directly fitted into holes, this would result in increased transmission resistance. Additionally, after wear and tear, these components would be difficult to replace. In contrast, bearings facilitate the support of transmission parts via rolling contact, thereby reducing friction and simplifying the replacement of worn components.

Therefore, it has the characteristics of low sliding resistance, low power consumption and easy starting. Its main function is to support the rotating body of machinery, reduce the friction coefficient during its movement, and ensure its rotational accuracy. It can be understood as it is used to fix the shaft, allowing it to only achieve rotation, while controlling its axial and radial movement. If the shaft has no bearings, it simply cannot work. Because the shaft may move in any direction, but during operation, it is required that the shaft can only rotate. Bearings have a wide range of applications. In automobiles: rear wheels, transmissions, electrical device components. In electrical appliances: general motors, household appliances. Instruments, internal combustion engines, construction machinery, railway vehicles, handling and loading/unloading machinery, various industrial machinery. Machine tool spindles, agricultural machinery, high-frequency motors, steam turbines, centrifugal separators, small car front wheels, differential small gear shafts. Oil pumps, Roots blowers, air compressors, various transmissions, fuel injection pumps, printing machinery, electric motors, generators, internal combustion engines, steam turbines, machine tool spindles, reduction devices, handling and loading/unloading machinery, various industrial machinery, etc. Almost anything that rotates can use bearings.
