Best Ceramic Ball Silicon Nitride Balls Supplier | Xingruida

​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 performance of electric and magnetic insulation. Its density is 3.20g/cm3, which is almost 1 / 3 of the bearing steel. Its weight and centrifugal force are small when rotating. It can realize high-speed operation. [1]

It can be used in the environment without high pollution of lubricating medium. Become the preferred material of ceramic bearing and hybrid ceramic ball bearing. Zirconia ceramic ball has high strength and toughness, good wear resistance, high temperature and corrosion resistance, high stiffness, non-magnetic and electrical insulation at room temperature. When the temperature is 600 ℃, the strength and hardness of zirconia ceramic ball are almost the same. The density of zirconia ceramic ball is 6.00g/cm3, and the thermal expansion rate is close to that of metal. If the thermal expansion rate is close to that of metal, zirconia ceramic ball can be used in conjunction with metal.
