The bearing ring and rolling element materials are made of AlSI SUS440C, 316L or 304 stainless steel, and the cage and sealing ring skeleton materials are made of AISI304 or 316L stainless steel. 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 -60C to 300C. Stainless steel bearings are widely used in various fields such as household appliances, motors, electric tools, fitness equipment, instruments, fishing gear, high-end toys, semiconductors, petroleum, chemical, electronics, electroplating equipment, textiles, food, medical, navigation, aerospace, doors and windows furniture, bathroom, etc. due to their high mechanical strength, large load capacity, high rotational speed, and resistance to acid, alkali, salt, and gas erosion.
