Detailed Photos

Silicon nitride ceramic balls can be used in various bearings with performance requirements: 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 and measuring balls.

 

Silicon nitride balls are designed for high-precision applications, featuring self-lubricating, high rigidity, non-magnetic conductivity, and low thermal conductivity.

•Super high strength •High temperature resistance •Acid and alkali resistance •Insulated and non-magnetic


 

 

Application of si3n4 balls:


Most ceramic balls are mounted in the bearing (high-speed bearing, high precision bearing, vacuum bearing, high/low-temperature bearing, nonmagnetic bearing, high precision ball screws) for the high technology industry, such as aerospace and national defense and etc. The ceramic balls can also be used for chemistry, metallurgy, medical treatment, food industry, oilfield, electronic engineering and etc.
