Silicon nitride ceramic balls

Silicon nitride ceramic balls are precision ceramics sintered at high temperature in a non-oxidizing atmosphere. They have high strength, high wear resistance, high temperature resistance, corrosion resistance, acid and alkali resistance, can be used in seawater for a long time, and have electrical and magnetic insulation properties. Good performance. At 800°C, the strength and hardness are almost unchanged, and its density is 3.20g/cm3, which is almost 1/3 of the weight of bearing steel. The centrifugal force is small during rotation, allowing high-speed operation. It is also self-lubricating and can be used in highly polluted environments without lubricating media. Become the first choice material for ceramic bearings and hybrid ceramic ball bearings. Zirconia ceramic balls have high strength and toughness at room temperature, good wear resistance, high temperature resistance and corrosion resistance, high stiffness, non-magnetic conductivity, and electrical insulation. When the zirconia ceramic ball is at 600°C, its strength and hardness are almost unchanged, its density is 6.00g/cm3, its thermal expansion rate is close to that of metal, and it can be used in conjunction with metal.
