Si3N4 ceramic balls bearing
Si3N4 ceramic balls are precision ceramics sintered at high temperature in non-oxidizing atmosphere.
They have high strength, high abrasion resistance, high temperature resistance, corrosion resistance, acid resistance, alkali resistance and can be used in seawater for a long time. At 800 ℃, the strength and hardness is almost the same, its density is 3.20 g/cm3, is almost 1/3 of the bearing steel. Weight, rotating centrifugal force small. Can realize high-speed operation. It also has self-lubricating property, which can be used in highly polluted environment without lubricating medium. Become the first choice ball ball ball ball ball of ceramic bearing and mixed ceramic ball bearing.
