Ceramic Bearing is extensively applied to the mechanical industry, and the traditional bearing usually adopts the material made of the bearing steel( GCr15) . Pottery compared with traditional bearing steel, has lower density, higher hardness, better wear-resisting and corrosion-resisting, which can bear high temperature, diamagnetism, insulating quality and lubricating nature, etc.
The structure with the ceramic bearing can be well used extensively since it is very Light as well as its low bloated coefficient , high rotational speed , low noise and long longevity featuring a outstanding characteristic Si3N4 ceramic bearing is used extensively in top-grade lathe, automobile , airplanes , conveying machinery , vacuum machinery and general machinery . Si3N4 ceramic bearing is the best choice in high-speeded rotating machines, such as high speed motorized spindle bearings, main shaft bearings of machine tools, dental drill bearings and computer hard disk drive bearing and so on. For solving corrosion problems, the ceramic bearings are often adopted in chemical machinery, food industry and marine industry.
