Support Media Ceramic ball with High Temperature Resistance

Support Media Ceramic Ball with High Temperature Resistance
Si3N4 is a new kind of bearing material with several good features, it possesses high temperature resistance, corrosion resistance, insulation, non-magnetism, high strength, low density and other features. 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.
The high precision and high performance silicon nitride bearing ball is manufactured by  spray-drying process, near-net-shape, cold isotatic pressing, GPS-HIP combined sintering, compounded abrasive lapping process effectively. The precision grade of it is G5, the materials class is I.
