Ceramic bearing advantages and applications

1. Since ceramics are hardly corrosive, ceramic rolling bearings are suitable for operation under the harsh conditions of corrosive media.

2. Since the density of the ceramic rolling ball is lower than that of the 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 prolonged.

3. The influence of thermal expansion and contraction of ceramics is smaller than that of steel. Therefore, when the clearance of the bearing is constant, the bearing can be allowed to work in an environment where the temperature difference changes drastically.

4. Since the modulus of elasticity of ceramic is higher than that of steel, it is not easy to deform when subjected to force, so it is beneficial to increase the working speed and achieve higher precision.

The above advantages can be simply summarized as corrosion resistance, long service life, high and low temperature resistance, high speed. In addition, ceramic bearings also have the characteristics of wear resistance, insulation and self-lubrication. Because ceramic bearings have such outstanding advantages, they are becoming more and more widely used in the industry, and the research on ceramic bearings has been further developed.

Today's ceramic bearings can be widely used in aviation, aerospace, marine, petroleum, chemical, electronic equipment, metallurgy, electric power, pumps, medical equipment, scientific research and defense and military fields, and are high-tech products for new materials applications. Of course, with the advancement of science and technology and the continuous improvement of the technological level, the research on ceramic bearings will continue, and the future ceramic bearings will develop even better.
