608 zz Hybrid Ceramic Bearing For Rollerskate With High Speed
Description of 608 zz Hybrid Ceramic Bearing:
Races can be chosen among GCr15 bearing steel, M50 steel, 440C stainless steel, high temperature resistant bearing steel, etc., fit with high precision G5 grade silicon nitride balls, which are treated with HIP (Hot Isostatic Pressure) sintering technology. Besides, fit with nylon cage or stainless steel cage and stainless steel single seal.
Performance advantages of 608 zz Hybrid Ceramic Bearing:
The Si3N4 balls have such advantages, such as small volume density, light weight structure, resistance to dry friction, low coefficient of linear expansion, self-lubrication, high fatigue life, wear-resistance, resistance to a variety of strong acid, strong alkali, salt corrosion (in addition to hydrofluoric acid, nitric acid), non-magnetic, non-conductive, high insulation.
Main application of 608 zz Hybrid Ceramic Bearing:
The 608zz bearing adopts the material matching of silicon nitride ball assembled in stainless steel races, which can guarantee the smooth performance of silicon nitride and have the impact resistance of GCr15 steel at the same time. It is high quality and cheap, and is the first choice for speed roller skating bearings.
