Stainless steel ball bearing usually made of 440(9Cr18) or 420(9Cr13) stainless steel, and sometimes 316 stainless steel for special applications. Comparing to chrome steel (Gcr15) ball bearings, stainless steel ball bearings can resist corrosion caused by moisture or acids. The stainless steel bearings have obvious advantages of stable operation, low noise, low magnet, wide application, better anti-corrosion and anti-rust properties, but it is also more difficult in production and requires stricter quality control than chrome steel ball bearings, so its price is relatively higher than the chrome steel one.
