Ceramic balls are precision ceramics sintered at high temperature in a non-oxidizing environment, with high strength, high abrasion resistance, high temperature resistance, acid and alkali resistance, and can be used in seawater for a long time, and has a good performance of adiabatic and adiabatic magnetism.At 800C, the strength and hardness are almost unchanged, and its density is 3.20g/cm3, almost 1/3 the weight of bearing steel. High speed operation can be achieved.It is also self-lubricating and can be used in environments with high pollution without lubricating media.Becoming a ceramic bearing, hybrid ceramic ball bearing application ball beads.
