Silicon Nitride Ceramic ball

Silicon Nitride Ceramic Balls (Si3N4) ceramic high strength, good wear resistance, high stiffness, corrosion resistance, high temperature, suitable for high temperature structural materials. Comparing the three types of ceramic materials, Si3N4 integrated superior performance, has become the material of choice for ceramic bearings.Application Composite bearings, mechanical seals, chemical pumps, nozzles, auto parts, heat exchange components, vacuum equipment and a variety of harsh environment.
