The stainless steel bearings not only have the characteristics of the ordinary bearings:low vibration, low noise,high precision rotating, lower friction torque and high speed running.But also have its special usage function:the range of application is wide ,it acid-proof and alkali-proof,and can bear ghe corrosive, can work in corrosion medium such as sea water,river aqua,distilled water, sparse nitric acid, maritime climate, steam and so on, it can work in the high or low temperature environment,within the scope of -253℃～350℃ temperature usage
