Features：
1. 【Corrosion-resistant strong acid, strong alkali】
Silicon nitride ceramic ball is a high-temperature sintered high-precision ceramic in a non-oxidizing atmosphere. It has high strength, high wear resistance, high temperature resistance, corrosion resistance, acid and alkali resistance, long-term use in seawater, and electric insulation. 
2. 【Light weight, high strength】
1/4 lighter than the general material of steel, its density is 3.20g/cm³ high steel, It is almost 1/3 of the weight of the bearing steel. Its hardness is twice as high as bearing steel. The centrifugal force during rotation is small. It can achieve high speed operation. 
3. 【High temperature resistance】
Strength and hardness are almost unchanged at 1000℃. Non-conductive, insulating, magnetic field can be used, non-conductive. Also has self-lubricating properties

Range of applications：
1. Silicon nitride ceramic balls are generally assembled into hybrid bearings, which can be used in high-tech industries such as aviation and national defense, and can also be widely used in chemical industry, metallurgy, medical treatment, food, oil field, electronics and other industries.
2. Silicon nitride ceramic balls can be used in various bearings with extreme performance requirements: high-speed/ultra-high-speed bearings, high-precision bearings, vacuum bearings, high/low temperature bearings, non-magnetic bearings, high-precision ball screws; they can also be used in chemical pumps , High temperature pumps, metering pumps are used as valve balls, swimming valves, fixed valves, and measuring balls.
