Features: At 800°C, the strength and hardness are almost unchanged. Its density is 3.20g/cm³, which is almost 1/3 of the weight of bearing steel. The centrifugal force is small during rotation and high-speed operation can be achieved. It also has self-lubricating properties, and it can be used in environments where no lubricating medium is highly polluted. It can be applied to high-precision hybrid ceramic bearings and full ceramic bearings. High precision, good wear resistance, high temperature resistance, high toughness, corrosion resistance, high rigidity, non-magnetic, electrical insulation, smooth surface, easy to clean.

Application: Semiconductor, LCD manufacturing equipment, electroplating equipment, synthetic fiber manufacturing equipment, optical film equipment, various heat treatment furnaces, vacuum equipment, etc.; can also be used for composite bearings, cold work tools, various guide wheels, various valves, vacuum equipment And various harsh environments.

Note: Compared with steel, silicon nitride ceramic ball is lighter than steel, has a lower friction coefficient, and has better sports performance. Its elastic modulus is 50% larger than that of steel. Not only that, the thermal expansion coefficient of silicon nitride is less than 25% of steel. It can maintain high strength and hardness before 1000°C at high temperature, is corrosion-resistant, does not rust, is non-magnetic, and can work under oil-free lubrication conditions.
