Products Description

Feature of Ceramic ball: 1, corrosion resistance, strong acid and alkali, seawater can also be used. 2, light weight, 1/4 lighter than the general material bearing, its density is 3.20g / cm3. 3, high rigidity, high strength, its hardness is twice as high as the bearing class, and the elastic modulus is about 1/3. 4, high-speed rotation, rotating body (the weight of the ball is light, the centrifugal is small when rotating. Silicon nitride ceramic ball is a kind of precision ceramic sintered at high temperature in non-oxidizing atmosphere. It has high strength, high wear resistance, high temperature resistance, corrosion resistance, acid and alkali resistance. It can be used in seawater for a long time, and has good properties of insulation. At 800 C, the strength and hardness are almost unchanged, and its density is 3.20g/cm3, which is almost 1/3 of bearing steel. Small weight and small centrifugal force in rotation can achieve high speed operation. It is also self-lubricating, it can be used in the environment without high pollution of lubricating medium. It is the preferred material for ceramic bearings and mixed ceramic ball bearings.
