Miniature ceramic bearing 686CE

Advantages of miniature ceramic bearing:

First, because ceramics are almost not afraid of corrosion, so ceramic rolling bearings are suitable for the harsh conditions in which corrosive media.

Second, 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, thus greatly extending the service life.

Thirdly, ceramic is less affected by thermal expansion and cold contraction than steel, so when the bearing clearance is fixed, the bearing can be allowed to work in the environment with more drastic temperature difference.

Fourth, because the elastic modulus of ceramics is higher than that of steel, it is not easy to deform under stress, so it is conducive to improving the working speed and achieving higher accuracy.

Ceramic bearing is mainly used for high temperature resistance, cold resistance, wear resistance, corrosion resistance, anti-magnetoelectric insulation, oil-free self-lubrication, high speed and other characteristics. It is widely used in aviation, aerospace, navigation, petroleum, chemical industry, automobile, electronic equipment, metallurgy, electric power, textile, pump, medical equipment, scientific research, national defense and military and other fields.
