Product details

Si3N4 ceramic ball PerformanceZYS silicon nitride ceramic (Si3N4) is a new kind of bearing material ,the material haveseveral good features,, it possesses high temperature resistance, corrosion resistance, insulation, non-magnetism, high strength, low density. In the application of bearing, it possesses low friction, low temperature rise, high rigidity, low centrifugal force and other features. It can implement high speed, high precision, high temperature, high rigidity, corrosion resistance and other good features.?ZYS ceramic ball with high precision and high performance ?is manufactured by ?spray-drying process, near-net-shape, cold isotatic pressing, GPS-HIP combined sintering, compounded abrasive lapping process effectively.
