Silicon nitride ceramic ball is a high-temperature sintered high-precision ceramic in a non-oxidizing atmosphere. It has high strength, high wear resistance, high temperature resistance, corrosion resistance, acid and alkali resistance, long-term use in seawater, and electric insulation. Good performance. It is almost 1/3 of the weight of the bearing steel. The centrifugal force during rotation is small. It can achieve high speed operation. Also has self-lubricating properties.  

At 800°C, the strength and hardness are almost unchanged, and its density is 3.20g/cm3, which is almost 1/3 of the bearing steel. Weight, the centrifugal force is small during rotation, high-speed operation can be achieved, and it is self-lubricating. Used in an environment with no lubricating medium and high pollution. It can be applied to high-precision hybrid ceramic bearings and full ceramic bearings.
