G5 Ceramic Balls Si3N4 Silicon Nitride Ball Ø 0.8mm-25.4mm Grade 5 Bearing BallsG5 Ceramic Balls Si3N4 Silicon Nitride Ball Grade 5 Bearing Balls Ø 0.8mm-25.4mm Product Name: ceramic ballMaterial: silicon nitride (Si3N4)Accuracy: Grade 5（G5）Diameter: 0.8mm – 25.4mm (According to your choice)Product features: high temperature, low temperature and corrosion resistanceApplicable medium: sealed insulated bearing medical devices Silicon nitride ceramic ball is a 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 electrical and magnetic insulation. 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. When rotating, the centrifugal force is small. It can realize high-speed operation. It also has self lubrication, which can be used in the environment with high pollution of non lubricating medium. Zirconia ceramic ball has high strength and toughness, good wear resistance, high temperature and corrosion resistance, high stiffness, non-magnetic conductivity and electrical insulation at room temperature. At 600 ° C, the strength and hardness of zirconia ceramic ball are almost unchanged. Its density is 600gcm3, and its thermal expansion rate is close to that of metal. If the expansion rate is high, it can be used in conjunction with metal. Due to the different display and different light, the picture may not reflect the actual color of the item.
