7300 Series Ceramic Angular Contact Balls Bearings In Material Of Si3N4/SSiC/ZrO2
Production technologies of cerami material:
1. Our zirconia material are made by highly purified, sub-micron and after Y2O3-TZP stabled zirconia powder material, are processed by AP (Atmospheric Pressure) sintering and HIP (Hot Isostatic Pressure) sintering technology.
2. Our silicon nitride bearings are made of highly purified, submicron silicon nitride powder with an alpha phase of more than 92%, and is processed by GPS (Gas Pressure) sintering and HIP (Hot Isostatic Pressure) sintering technology.
3. Our silicon carbide bearings are made of highly purified, sub-micron silicon carbide material. The atmospheric pressure solid phase sintering method at a high temperature of 2250°C are used to produce SSiC (Sintering SiC), so the free silicon and free carbon in the products are close to the theoretical values and can resist corrosion of fast all kinds of acid and alkali.
