stainless steel ball bearings suppliers SMR115-2RS

Stainless steel ball bearing are also called stainless steel ball bearings or stainless steel bearings or stainless ball bearings. Usually,the stainless steel used in ball bearings are belong to a martensitic-type stainless steel which can meet the needs in bearings hardness,corrosion resistance and dimensional stability.

 Compared with ordinary chrome steel ball bearing, Stainless steel ball bearing can keep from corrosion caused by some acids or moisture,and stainless steel ball bearing have obvious advantages of stable operation, low noise, low magnet, wide application, excellent anti-corrosion and anti-rust properties.   But stainless steel ball bearing are more difficult and strict than ordinary bearings in technology and precision control.

   Stainless steel ball bearings can be widely used in the fields of medical equipment, cryogenic engineering, optical instruments, high-speed machine tools, high-speed motors, precision clocks,printing machinery, wind speed measuring instruments, food processing machinery, scanners and fishing reels etcs.

Stainless steel ball bearing are just suitable for applications in little corrosive environments , corrosive environments with seawater,stronger alkalis and stronger acids are not recommended,it will greatly affected the corrosion resistance of stainless steel ball bearing.
