Compared with ordinary bearings, stainless steel bearings not only have obvious advantages in material, but also have much stricter control over process and accuracy. Stainless steel bearings work stably, with low noise, corrosion resistance, and are widely used in the working process. The bearing ring and rolling element materials are made of AISI SUS440C stainless steel (domestic grades: 9Cr18Mo, 9Cr18), which has undergone vacuum quenching and tempering treatment. The cage and sealing ring skeleton materials are made of AISI304 stainless steel (domestic grade: OCr18Ni9). Compared with ordinary bearing steel, stainless steel bearings have stronger rust and corrosion resistance. By selecting appropriate lubricants, dust covers, etc., they can be used in environments ranging from -60 ℃ to+300 ℃. Stainless steel deep groove ball bearings can resist corrosion caused by moisture and several other media. This type of single row deep groove ball bearing, like the standard deep groove ball bearing made of carbon chromium (rolling bearing) steel, has a very deep bearing raceway groove, and the fit between the bearing raceway and the ball is extremely high. Stainless steel bearings are widely used in food processing, medical equipment, and pharmaceutical machinery due to their high mechanical strength and high load capacity.
