The ring and rolling body of ceramic bearing are made of all-ceramic materials, including zirconia (ZrO2), silicon nitride (Si3N4) and silicon carbide (Sic). The retainer is made of polytetrafluoroethylene, nylon 66, polyetherimide, zirconia, silicon nitride, stainless steel or special aviation aluminum, thus expanding the application surface of ceramic bearings.

Zirconia: Zirconia ceramic bearing with magnetoelectric insulation, wear resistance and corrosion resistance, oil-free self-lubrication, high temperature and cold resistance and other characteristics, can be used in extremely harsh environment and special conditions. The ring and rolling body are made of zirconia (ZrO2) ceramic material, the retainer uses polytetrafluoroethylene (PTFE) as the standard configuration, and generally can also use glass fiber reinforced nylon 66 (RPA66-25), special engineering plastics (PEEK, PI), stainless steel (AISISUS316), brass (Cu) and so on.

Advantages:

1. Because ceramics are almost not afraid of corrosion, ceramic rolling bearings are suitable for operation under harsh conditions covered with corrosive media.

2. Because the density of ceramic rolling ball is lower than that of steel, the weight is much lighter, so the centrifugal effect of the outer ring can be reduced by 40% when rotating, and the service life is greatly extended.

3. Ceramic is less affected by thermal expansion and contraction than steel, so when the bearing clearance is fixed, the bearing can be allowed to work in an environment where the temperature difference is more drastic.

4. Because the elastic modulus of ceramics is higher than that of steel, it is not easy to deform when stressed, so it is conducive to improving the working speed and achieving higher accuracy.
