SUS304/SUS316L austenitic stainless steel bearings have good corrosion resistance and temperature resistance, and non-magnetic. It can be used in the harsh environment of humidity, acid, alkali, salt and other chemical erosion or food-grade working conditions. It can be used in the operating temperature range of -253°~450°. Because austenitic stainless steel cannot be hardened as a whole, it is not suitable for large loads and high speeds.

Compared with ordinary steel bearings, S440C not only has obvious advantages in material, has stronger rust and corrosion resistance, but also in the process, precision control, more strict than ordinary bearings, stable in work, low noise. After quenching and tempering, the ring and rolling body have the characteristics of high mechanical strength, large load power and high speed, which are widely used in food processing, medical equipment and medicine machinery.
