GCr15 AISI440C Hybrid Ceramic Ball Bearings For Inner / Outer Ring
Hybrid construction ceramic ball bearings
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 working, the best choice for rollers (inner ring and outer ring are made by metal) of the hybrid construction ceramic ball bearing which are used in high-speed, high accuracy and long life environments. Normally, GCr15, AISI440C, 316, 304 makes inner ring and outer ring. The ceramic ball can adopt ZrO2, Si3N4 or Sic material.
