hybrid ceramic bearing 1.Inner and outer ring: GCr15 or AISI440C,316 304 2.the ball: ZrO2,Si3N4 or SiC

hybrid ceramic bearing

Ceramic ball especially Si3N4 have the following performance as low density ,high strength ,low friction coefficient ,electrical and magnetism resistance ,wear resistance ,well rigidity ,lubrication and maintenance free when free when working, it is the best choice for rollers(inner ring and outer ring are made by metal) for the hybrid construction ceramic ball bearing which are used in high speed, high accuracy and long life environment .Normally GCr15 or AISI440C,316 304 makes inner ring and outer ring; The ceramic ball can adopt ZrO2,Si3N4 or SiC.
