Hybrid Ceramic Roller Bearing of Steel Races+Ceramic Roller
Description of Hybrid Ceramic Roller Bearing:
Our company can volume produce hybrid ceramic roller bearings in material of steel races assembled with ceramic rollers The races can be chosen among stainless steel/ bearing steel or other steel you need and the rollers can be zirconia, silicon nitride and silicon carbide ceramic rollers. The hybrid ceramic ball bearing combines the nice wear resistance of steel and the excellent resistance to corrosion and good electric and magnetic insulation of ceramic material.
