✨ Introduction of Ceramic Balls
Silicon nitride ceramic ball and steel comparison, silicon nitride mass than steel light, coefficient of friction is small, good sports performance, modulus of elasticity than steel 50%, not only the coefficient of thermal expansion of silicon nitride is less than 25% of the steel, high temperature in the 1000 ℃ before the high strength and hardness, corrosion-resistant, non-rust, non-magnetic, can be in the oil lubrication under the conditions of work.
Silicon Nitride Ceramic Balls are precision ceramics sintered at high temperature in a non-oxidising atmosphere, with high strength, high abrasion resistance, high temperature resistance, corrosion resistance, acid resistance, alkali resistance, can be used for a long time in seawater, and has good performance of adiabatic and antimagnetic.
✨ Product Details
1.High precision - dimensional tolerance of ±0.0002mm, can be used in high standard of fine environment.
2.Self-lubricating - can solve the pollution caused by the lubricating medium and add inconvenience, can be in contact with food.
3.Non-magnetic insulation - indoor resistivity up to 1013 ohm cm when the temperature rises to 600 ℃ can conduct electricity.
4.Good corrosion resistance - in medium acid, medium alkali, seawater and other media can also be used.
5.High temperature resistance a high temperature of 1200 "C is not a problem; silicon nitride ceramic ball is in the non-oxidising atmosphere of high-temperature sintering of precision ceramic ball, after a long time and many times of grinding and processing, can withstand high temperatures of 1200 ℃
6.Hardness - At 800 ℃ , strength, hardness is almost unchanged, its density of 3.20g/cm3, almost 1/3 of the weight of the bearing steel, rotating centrifugal force is small. High speed can be achieved
✨ Application :

Silicon nitride ceramic ball can be used in a variety of extreme performance requirements of bearings: high-speed / ultra-high-speed bearings, high-precision bearings, vacuum bearings, high / low temperature bearings, non-magnetic bearings, high-precision ball screw; can also be used in chemical pumps, high-temperature pumps, metering pumps used as valve ball, travelling vanes, fixed vanes, measuring ball.
Silicon nitride ceramic balls are generally assembled into hybrid bearings, which can be used in high-tech industries such as aviation, national defence and other industries, and can also be widely used in other industries such as chemical, metallurgy, medical, food, oil field, electronics and so on.
