Compared with the ordinary bearings, the corresponding stainless steel bearings can be selected according to different working conditions while the ordinary steel bearings can not meet the case. Stainless steel bearings have unique performance and can adapt to the various environments, such as acid and alkali resistance, corrosion resistance and can work in seawater, river water, distilled water, dilute nitric acid, Marine climate, steam and other corrosive media. And it also has the characteristics of temperature resistance that the operating temperature range from -253°c to 350°c.
Cosmic bearings commonly used to make stainless steel bearings are: SUs440C, SUS304, SUS316L and so on. ASUS440C is martensitic stainless steel, SUS304, SUS316L is austenitic stainless steel. Because austenitic stainless steel is not quenched, the hardness is relatively poor, and the bearings of such materials are only suitable for low speed and light load occasions. Austenitic stainless steel has non-magnetic and corrosion resistance.
