Silicon Nitride Ceramic Balls
Silicon nitride ceramic balls have ultra-high hardness, wear resistance, corrosion resistance and high temperature stability, and are widely used in bearings, grinding media, sealing valves, nozzles, precision machinery and other fields. We provide a variety of materials such as silicon nitride, silicon carbide, zirconium oxide, aluminum oxide, etc. to meet the needs of different working conditions.
Suitable for: high precision bearings, grinding media, fluid control, corrosion resistant filling materials and other applications.
- High wear resistance – far exceeding metal balls, suitable for high wear environments.
- High temperature & corrosion resistance – suitable for extreme working conditions, such as chemical, marine, energy and other industries.
- High precision & low friction – up to G3 level accuracy, surface finish Ra0.02 (specific accuracy depends on material & diameter, see technical specifications below for details).
- Customization support – different diameters, tolerance ranges and special coatings are available.
