Zirconia Double-Row Self-Aligning Ball Bearings With Cylindrical Bore
Description of ZrO2 material:
Our zirconia material are made by highly purified, sub-micron and after Y2O3 partially
stabled zirconia powder and 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, to
which is the ordinary zirconia bearings incomparable.
►Key properties of zirconia |
♦ Max Temperature up to 380℃ |
♦ High density: 6.09 g/cm3 |
♦ Low thermal conductivity |
♦ Chemical stability, resistance to acid and alkali corrosion |
♦ High fracture toughness KIC:8-11 MPa-m1/2 |
♦ Good electric insulation |
♦ Better bearing capacity |
♦ Wear resistance |
♦ High hardness : 1300 HV5 |
