6000 Ce In Material Of ZrO2 Rings+Si3N4 Balls+PTFE Cage
Description of 6000CE (ZrO2 Races+Si3N4 Balls+PTFE Cage):
1. ZrO2 rings: 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.
2. Si3N4 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. So the porosity is declined and the wear resistance, crushing value and fatigue contact life are greatly improved, which is the preferred material for ultra-high speed and high precision ceramic bearings.
3. PTFEcage: Teflon has excellent chemical stability, can resistant to molten metal sodium and liquid fluorine, to all kinds of acid and alkali resistance and organic solvent,can work in +250℃ to -180℃ temperature for a long time.
Performance advantage of 6000CE (ZrO2 Rings+Si3N4 Balls+PTFE Cage):
Because of following properties of material, the load of 6000 Ce in this material combination is 4100 N(Cr) and 1960 N(Cor) and its maximum operating speed can reach 37700 rpm with grease lubrication and 44200 rpm with oil lubrication.
