Feature of Ceramic ball:
1, corrosion resistance, strong acid and alkali, seawater can also be used.
2, light weight, 1/4 lighter than the general material bearing, its density is 3.20g / cm3.
3, high rigidity, high strength, its hardness is twice as high as the bearing class, and the elastic modulus is about 1/3.
4, high-speed rotation, rotating body (the weight of the ball is light, the centrifugal is small when rotating.



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 properties of insulation. At 800ºC, the strength and hardness are almost unchanged, and its density is 3.20g/cm3, which is almost 1/3 of bearing steel. Small weight and small centrifugal force in rotation can achieve high speed operation. It is also self-lubricating, it can be used in the environment without high pollution of lubricating medium. It is the preferred material for ceramic bearings and mixed ceramic ball bearings.

Our company produces G3 grade high precision Si3N4 silicon nitride ceramic ball. Compared with traditional steel ball bearings, Si3N4 ceramic ball bearings have many advantages: small starting torque, long service life, high rigidity, insensitive to temperature, good self-lubrication, good insulation and good corrosion resistance. Ceramic material itself has extremely high acid and alkali resistance, seawater resistance, salt spray performance is very strong, with special alloy steel processing bearing has perfect corrosion resistance and high temperature resistance. The company mainly produces and sells Φ50.8mm high-precision silicon nitride ceramic ball, accuracy can reach G3 level.
