Customized silicon carbide ceramic ball for ceramic rolling bearings with high precision
Description of SSiC Ceramic Bearing Ball:
Our silicon carbide balls are made of highly purified, sub-micron silicon carbide material. We sintered the silicon caibide with pressureless sintering method, so the properties of silicon carbide are highly improved after our sintering technology, whose properties are besser than reactive sintering technology and porosity is lower. Because of the excellent of silicon carbide, ceramic bearing balls in this material are always fitted in ceramic rolling bearings in same material, which is widely used in petroleum, chemical, semiconductor and food machinery indurtry because of its excellent corrosion resistance.
| ►Key properties of pressureless sintered silicon carbide |
| ♦ Max Temperature up to 1650℃ |
| ♦ Low density:3.15-3.18 g/cm3 |
| ♦ High strength |
| ♦ Low thermal expansion : 4.0 (10-6/℃) |
| ♦ High thermal conductivity:120 W/m°K |
| ♦ High hardness:2800 HV5 |
| ♦ High elastic modulus: 410GPa |
| ♦ Superior chemical stability,resistance to acid and alkali corrosion (incld. hydrofluoric acid) |
