Ceramic bearings have the characteristics of high temperature resistance, cold resistance, wear resistance, corrosion resistance, anti-magnetic electrical insulation, oil-free self-lubrication, high speed, etc.. Can be used in its harsh environment and special working conditions, can be widely used in aviation, aerospace, navigation, petroleum, chemical industry, automotive, electronic equipment, metallurgy, electric power, textile, pumps, medical equipment, scientific research and national defense military and other fields, is a new material application of high-tech products.

Ceramic bearing ring and rolling body using full ceramic materials, there are zirconium oxide (ZrO2), silicon nitride (Si3N4), silicon carbide (Sic) three. The retainers are made of PTFE, nylon 66, polyetherimide, zirconium oxide, silicon nitride, stainless steel or special aerospace aluminium, thus expanding the application of ceramic bearings.

Since ceramics have little fear of corrosion, ceramic rolling bearings are suitable for operation in harsh conditions where corrosive media are present. As the density of ceramic rolling ball is lower than steel, the weight is much lighter, so the centrifugal effect on the outer ring when rotating can be reduced by 40%, and thus the service life is greatly extended, because the elastic modulus of ceramic is higher than that of steel, it is not easy to deform when under force, so it is conducive to improving the working speed and achieving higher precision.
