Silicon nitride ceramic balls are precision ceramics sintered at high temperature in a non-oxidizing atmosphere.
They have high strength, high wear resistance, high temperature resistance, acid and alkali resistance, can be used in seawater for a long time, and have good performance.
At 800℃, the strength and hardness are almost unchanged, and its density is 3.20g/cm3, which is almost 1/3 of the weight of the bearing steel.
The centrifugal force is small when rotating. High-speed operation can be achieved.
It is also self-lubricating, and can be used in environments without lubricating media.It is made of ceramic bearings and mixed ceramic ball bearings.
