ceramic balls are precision ceramics sintered at high temperature in non-oxidation atmosphere, with high

strength, high wear resistance, high temperature resistance, corrosion resistance, acid, alkali resistance, can be used in

seawater for a long time, and has excellent performance of no electricity and no magnetism. At 800℃, the strength and hardness are almost unchanged, and its density is 3.30g/cm3, which is almost 1/3 of bearing steel. Weight, low centrifugal force in rotation. Can achieve high speed operation. It is also self-lubricating and can be used in environments with high pollution without lubricating media. It is an ideal material for ceramic bearing and mixed ceramic ball bearing.
