High Polished Silicon Nitride Durable Bearing Balls
Description:
Si3N4 is a new kind of bearing material with several good features, it possesses high temperature resistance, corrosion resistance, insulation, non-magnetism, high strength, low density and other features. In the application of bearing, it possesses low friction, low temperature rise, high rigidity, low centrifugal force and other features. It can implement high speed, high precision, high temperature, high rigidity, corrosion resistance and other good features. The high precision and high performance silicon nitride bearing ball is manufactured by spray-drying process, near-net-shape, cold isotatic pressing, GPS-HIP combined sintering, compounded abrasive lapping process effectively.
Technical Parameters:
| Mechanical behavior | Unit | Al2O3 | SiC | Si3N4 | ZrO2 |
| Colour | ------- | Light yellow | black | black | white,black |
| Density | g/cm3 | 3.95 | 3.15 | 3.2 | 6 |
| Bending strength | MPa | 300～400 | 400～500 | 800～1200 | 950～1200 |
| Elastic modulus E | GPa | 380 | 350 | 300-320 | 210 |
| Poisson's ratio | 0.22 | 0.14 | 0.26 | -------- | |
| Hardness | Hv | 1800 | 2000～2500 | 1400～1700 | 1100～1300 |
| HRC | 80 | 85～90 | 75～80 | 70～75 | |
| Fracture toughness | MPa·m1/2 | 3.0～4.0 | 3.0～4.0 | 5.0～7.0 | 8.0～10.0 |
| Maximum use temperature | ℃ | 1000 | 1300 | 400 | 400 |
| Thermal expansion coefficient | 10-6/℃ | 8.4 | 4 | 3.3 | 10.3 |
Advantages:
1. corrosion resistance, strong acid and alkali, seawater can also be used.
2. light weight, 1/4 lighter than the general material bearing, its density is 3.20g / cm3.
3. high rigidity, high strength, its hardness is twice as high as the bearing class, and the elastic modulus is about 1/3.
4. high-speed rotation, rotating body (the weight of the ball is light, the centrifugal is small when rotating.
Application:
Composite bearings, mechanical seals, chemical pumps, nozzles, automotive parts, heat Switch parts, vacuum equipment, etc. and in a variety of harsh environments.
