Application: Silicon nitride balls can be used in bearings which need Extreme performance requirements: highspeed/ superspeed bearings, high precision bearings, vacuum bearings, high/ low temperature bearings, non-magnet bearings, high-precision ball screw; also can be used as valve ball, measurement ball in chemical pump ,high-temperature pump, metering pump. And it can be used in slide and measurement such as: high temperature slide trail and anti-corrosion slide trail.
Product feature: stable performance, good consistency.
Product standard: 0.4mm~100mm
Provide grade: G3~G60 notes
1）Most are black silicon nitride balls, if necessary, we can also provide gray ones.
2）We have mass stock, can deliver anytime you want.
3）Can meet the requirements of various specifications and non-standard sizes.
