Ceramic bearing has the characteristics of high temperature resistance, cold resistance, abrasion resistance, corrosion resistance, magnetoelectricity resistance, insulation, no oil self-lubricating and high rotational speed. Ceramic bearing can be used in the field of aviation, spaceflight, navigation, petroleum, chemical industry, automobile, electronic equipment, metallurgy, electric power, textile, pumps, medical equipment, scientific research and defense military. Ceramic bearing rings and roller elements adopt full ceramic materials, zirconium oxide (ZrO2), Si3N4 (Si3N4) and silicon carbide (Sic), and the cage adopts perfluoroethylene, nylon 66, zro2, si3n4, stainless steel or special aviation aluminum.
