Ceramic thrust ball bearing 51204CE
Advantages of porcelain bearing:
Firstly, because the elastic modulus of ceramics is higher than that of steel, it is not easy to deform under stress, so it is beneficial to improve working speed and achieve higher accuracy. Second, because ceramics are almost impervious to corrosion, ceramic rolling bearings are suitable for working in harsh conditions with corrosive media. Thirdly, ceramic is less affected by thermal expansion and cold contraction than steel, so when the bearing clearance is fixed, it can allow the bearing to work in the environment with drastic temperature difference. Fourth, because the density of ceramic rolling ball is lower than that of steel, the weight is much lighter, so the centrifugal action of the outer ring can be reduced by 40%, thus the service life is greatly extended.
Main application areas
Ceramic bearings have high temperature resistance, cold resistance, wear resistance, corrosion resistance, resistance to magnetoelectric insulation, oil free self-lubrication, high speed and other characteristics. Can be used in extreme harsh environment and special working conditions, can be widely used in aviation, aerospace, navigation, petroleum, chemical industry, automobile, electronic equipment, metallurgy, electric power, textile, pump, medical equipment, scientific research and national defense and other fields, is a new material application of high-tech products. Ceramic bearing ring and rolling body using all ceramic materials, zirconia (ZrO2), silicon nitride (Si3N4), silicon carbide (Sic) three kinds. The retainer is made of ptfe, nylon 66, polyetherimide, zirconia, silicon nitride, stainless steel or special aviation aluminum, thus expanding the application of ceramic bearings.
