Bearing material selection affect bearing performance: When the detection of chromium bearing steel and stainless steel as a material advantage, and found them not only with rust eff ect. Chromium bearing steel is the most common material. It is harder than stainless steel, so longer. However, at higher temperatures, its performance is not how.bearing roller bearings
At 120C under a high temperature, it will happen enormous deformation, the load decreases. Sustained high temperatures it can tolerate 150C, 150C or higher but the moment the temperature will reduce bearing life. Heat treatment can make the bearings to withstand high temperature instantaneously 170C.
The most common stainless steel for the bearing 440, which hard and strong enough to load, (20% less than steel, brass), but it can rust and can tolerate high temperature 250C and 300C of the instant continuous high temperature. We often mistakenly thought that all of the stainless steel is not magnetic, 440 stainless steel is magnetic, it is not completely rust, but by salts, acids, alkalis. 316 levels of anti-rust per formance is very good, not magnetic, but relatively soft, low load, since it is not strong, so the accuracy of the bearing 316 is not high, feeling rough.deep grove ball bearing
