Zirconia Thrust Bearing 51111 Fitted With PTFE Cage
Description:
1. 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. After HIP sintered zirconia races and balls have higher density, besser properties and lower porosity.
2. PTFE cage: 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.
Material properties of zirconia:
♦High hardness : 1300 HV5 |
♦ High density: 6.09 g/cm3 |
♦ Max Temperature up to 380℃ |
♦ Chemical stability, resistance to acid and alkali corrosion |
♦ High fracture toughness KIC:8-11 MPa-m1/2 and good wear resistance |
♦ Low thermal conductivity |
♦ Better bearing capacity |
♦ Good magnetic and electric insulation |
