Ceramic Ball Bearing 6802 In Material Of SSiC/Si3N4/ZrO2
Description of Ceramic Bearing 6802:
1. SSiC races and balls are made of highly purified, sub-micron silicon carbide material. We sintered the silicon caibide with pressureless sintering method, so SSiC material have well corrosion resistance, high strengthm high hardness, wear resistance and small friction coefficient, antioxidant, small creep high temperature and good heat stability. So it's the ideal material for the ceramic bearings which are used in special conditions.
2. Si3N4 races and balls 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. ZrO2 races and balls 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, so their porosity, wear resistance, impact resistance and resistance to fatigue contact life are greatly improved
4. The material of cages can be chosen among Peek, Teflon, PFA and other material you required.
