ceramic bearing

   Ceramic bearings have the characteristics of high temperature resistance, cold resistance, wear resistance, corrosion resistance, anti-magnetic and electrical insulation, oil-free self-lubrication, high speed and so on. It can be used in extremely harsh environments and special working conditions, and can be widely used in aviation, aerospace, navigation, petroleum, chemical industry, automobiles, electronic equipment, metallurgy, electric power, textiles, pumps, medical equipment, scientific research and national defense military and other fields. High-tech products with new material application.

   First of all, because ceramics are almost not afraid of corrosion, ceramic rolling bearings are suitable for operating under harsh conditions full of corrosive media.

   The Second, because the density of ceramic rolling balls is lower than that of steel, the weight is much lighter, so the centrifugal effect on the outer ring can be reduced by 40% during rotation, and the service life is greatly extended. 

   The Third, ceramics are less affected by thermal expansion and contraction than steel, so when the clearance of the bearing is constant, the bearing can be allowed to work in an environment with severe temperature changes. 

   The Fourth, since the modulus of elasticity of ceramics is higher than that of steel, it is not easy to deform when stressed, so it is beneficial to improve the working speed and achieve higher precision.
