What are thin-wall bearings?

Thin-walled bearings mean that the ratio of the inner diameter and outer diameter of the bearing is less than a specified value. When the ratio of the bearing outer diameter to the bearing inner diameter is less than 1.25, it is called a thin-walled ball bearing. This means that the value of the bearing's outer diameter-inner diameter is very small and the bearing wall is very thin, so it is called a thin-walled bearing.

Thin-walled ball bearings require high precision. Because their walls are very thin, the weight they can carry is reduced, so the choice must be based on the use environment.

Thin-wall bearings have a simple structure and are easy to 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 combined radial and axial loads. When the rotational speed is high and thrust ball bearings are not suitable, thin-walled bearings with angular contact ball types can also be selected to bear pure axial loads. Compared with other types of bearings of the same size, thin-walled bearings have smaller friction coefficients and higher limit speeds.

This type of thin-walled bearings are mainly used in: industrial robots, medical equipment, textile machinery, radar, model aircraft, remote control vehicles, machine tools, motors, water pumps, agricultural machinery, laser printers, measuring instruments, electronic accessories, motors, motors, etc.
