Ceramic Thrust Bearing 51413 65x140x56mm All Silicon Nitride
All Silicon Nitride Ceramic Thrust Bearings 51413
Description of Si3N4 Ceramic Thrust Bearings 51413:
1. Si3N4 races balls: Are made of highly purified, submicron silicon nitride powder with an alpha phase of more than 92%, and is HIP (Hot Isostatic Pressure) sintering technology. 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. PEEK cage: The crown structure cages of PEEK material have high strength, light body. PEEK material has similar corrosion resistance to ceramic materials, and has a good resistance to radiation, self-lubricating properties, a high degree of wear resistance and other characteristics.
Performance advantages of silicon nitride material:
| ► Key properties of hot isostatic 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 electric insulation |
