Silicon nitride ceramic ball is a high-temperature sintered ceramic in a non-oxidizing atmosphere. It has high strength, high abrasion resistance, high temperature resistance, corrosion resistance, acid and alkali resistance, long-term use in seawater, Good performance. At 800 ℃, the strength, hardness is almost unchanged, the density of 3.20g / cm3, almost bearing steel 1 / 3. Weight, centrifugal force when rotating small. Can achieve high-speed operation. Also has a self-lubricating, it can be used to high-pollution environment without lubrication medium. Become a ceramic bearing, ceramic ball bearings mixed choice ball.
