Product descripiton：Silicon nitride ceramic ball is a precision ceramic sintering at high temperature in non-oxidizing atmosphere. It has high strength, high wear resistance, high temperature resistance, corrosion resistance, acid and alkali resistance, can be used in seawater for a long time, and has good performance of insulation and magnet. At 800℃, the strength and hardness are almost constant, and its density is 3. 20 g/cm3, which is almost 1 / 3 of the weight of the bearing steel, and the centrifugal force is small during rotation. It can be run at a high speed. It also has self-lubrication, which can be used in the environment without high pollution of lubricating media. Become a ceramic bearings, the preferred ball bead for mixed ceramic ball bearings.
