Si3N4 Ceramic Thrust Bearings Of Customized Model
Description of Si3N4 Ceramic Thrust Bearings:
1. Silicon Nitride ceramic thrust 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. Compared with GPS sintered silicon nitride material, the porosity, wear resistance, crushing value and fatigue contact life of after HIP sintered sinlicon nitride have been greatly improved, which is the preferred material for ultra-high speed and high precision ceramic bearings.
2. The material of cage can be chosen among PEEK, and Brass, we can customize any material combination according to your requirement.
Key properties of HIP-Si3N4 (Hot isostatic pressure sintered silicon nitride)
| ♦ Max temperature to 1000℃ |
| ♦ High strength over a wide temperature range |
| ♦ High fracture toughness: 6.1 MPa-m1/2 |
| ♦ High hardness: 1580 HV5 |
| ♦ Outstanding wear resistance, both impingement and frictional modes |
| ♦ Good thermal shock resistance |
| ♦ Good chemical stability,resistance to acid and alkali corrosion |
| ♦ Good magnetic and electric insulation |
