Thin-wall bearing is bearing diameter and diameter ratio is less than a specified value. The ratio of the outer diameter of the bearing and the inner diameter of the bearing is below 1.25, which is called thin-wall ball bearing. This means that the outer diameter - inner diameter of the bearing is very small, and the bearing wall is very thin, so it is called thin-wall bearing.

 

 

 

Thin-wall ball bearings require high accuracy, because their walls are very thin, the weight they can carry is reduced, so it should be chosen according to the use environment.

 

 

 

Thin wall bearing is simple in structure and convenient in use. It is mainly used to bear radial loads, but when the radial clearance of the bearing is increased, it has certain performance of angular contact ball bearings and can bear radial and axial combined loads. When the speed is high and the thrust ball bearing is not suitable, the angular contact ball type of thin-wall bearing can also be selected to bear pure axial load. Compared with other bearings of the same size, thin wall bearings have small friction coefficient and high limit speed.

 

 

 

This kind of thin wall bearings are mainly used in: industrial robots, textile machinery, radar, model aircraft, remote control vehicles, machine tools, motors, water pumps, agricultural machinery, laser printers, measuring instruments, electronic accessories, motors, motors and so on
