What is a thin-walled bearing?

Thin-walled bearings refer to bearings whose inner diameter to outer diameter ratio is less than the specified value. The ratio of the outer diameter of the bearing to the inner diameter of the bearing is less than 1.25, which is called a thin-walled ball bearing. This means that the value of the outer diameter of the bearing to the inner diameter is very small, and the bearing wall is very thin, so it is called a thin-walled ball bearing. Thin-walled bearings require high precision. Because the wall is very thin, the load-bearing capacity is also low, and the impact resistance is very poor. It should be selected according to the use environment!! Thin-walled ball bearings have a simple structure and are easy to use. They are mainly used to bear radial loads, but when the radial clearance of the bearing becomes larger, they have certain performance of angular contact ball bearings and can withstand combined radial and axial loads. When the speed is high and the thrust ball bearing is not suitable, it can also be used to bear pure axial loads. Compared with other types of bearings of the same size, this type of bearing has a small friction coefficient and a high speed. But it is not impact-resistant and is not suitable for heavy loads. It is widely used in industries such as aircraft, aerospace, astronomical instruments and clamping equipment, food processing equipment, glass production equipment and turntables, machine tools, packaging equipment, medical equipment, optical scanning equipment, radar, satellite communication equipment, textile machinery, robots and semiconductor manufacturing equipment.

Stainless steel thin-walled bearings are rust-proof and corrosion-resistant. Suitable for working in wet, underwater and other corrosive media environments, its products are widely used. Stainless steel thin-walled bearings have rolling elements and rings like other series of bearings, but they are all made of stainless steel, equipped with corresponding seals and cages, and can withstand radial, axial and overturning forces according to different structures. Stainless steel thin-walled ball bearings are flexible in rotation, stable in operation, have much less friction torque than sliding bearings, and have a long service life. However, the overall load-bearing capacity is slightly smaller than that of ordinary bearings.

　　Stainless steel thin-wall bearings mainly include large deep groove ball bearings and four-point thin-wall ball bearings, and the sealing structure can be opened or closed for users to choose.
