What are the advantages of ceramic bearings?


Ceramic bearing is an important mechanical basic part, which has excellent performance unmatched by metal bearings. Ceramic bearings have the characteristics of high temperature resistance, cold resistance, corrosion resistance, anti-magnetic electrical insulation, oil-free self-lubrication, high speed and so on. It can be used in extremely harsh environments and special working conditions. It can be widely used in aviation, aerospace, marine, petroleum, chemical, automotive, electronic equipment, metallurgy, electric power, textiles, pumps, medical equipment, scientific research and defense and military fields. High-tech products using new materials.
The ceramic bearing rings and rolling elements are made of all-ceramic materials, including zirconia (ZrO2), silicon nitride (Si3N4), and silicon carbide (Sic). The retainer is made of polytetrafluoroethylene, nylon 66 and other materials. Ceramic bearings have the following advantages:
1. Since the density of ceramic rolling balls is lower than steel, and the weight is much lighter, the centrifugal effect of the outer ring can be reduced by 40% when rotating, and the service life is greatly extended.
2. Since the elastic modulus of ceramic is higher than that of steel, it is not easy to deform when subjected to force, so it is conducive to improving the working speed and achieving higher accuracy.
3. Since ceramics are scarcely resistant to corrosion, ceramic rolling bearings are suitable for operation in harsh conditions covered with corrosive media.
4. Ceramic is less affected by thermal expansion and contraction than steel, so when the bearing clearance is constant, the bearing can be allowed to work in an environment where the temperature difference changes drastically.
