Product Description
Miniature ceramic deep groove balls bearings of Silicon Nitride
Description of Si3N4 Miniature Ceramic Deep Groove Balls Bearings:
Si3N4 races and balls: Are made of highly purified, submicron silicon nitride powder with an alpha phase of more than 92%, and is processed after HIP (Hot Isostatic Pressure) sintering technology. So the porosity, wear resistance, crushing value and fatigue contact life have been greatly improved.Silicon nitride bearings are suitable for high-speed, alternating load environment, so are usually use as high-speed spindle, electric spindle, CNC machine tool and motorized spindle bearings.
| ♦ 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 |
