Full Silicon Carbide Balls Ceramic Bearing 7004 With High Precision
SSiC races and balls: Are made of highly purified, sub-micron silicon carbide material, can resist corrosion by hydrofluoric acid, which is the most excellent ceramic material with the best corrosion resistance among the known materials.
Performance advantages of SSiC Bearing (Pressureless sintered silicon carbide):
With a density and coefficient of linear expansion close to that of silicon nitride ceramic materials, high hardness, wear resistance, resistance to various strong acids, strong alkalis, salt corrosion, high temperature resistance. SSiC all ceramic bearings are preferred structure for the petroleum, chemical, semiconductor, food machinery, pharmaceutical industry, etc., and are the most widely used ceramic bearings.
| ►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) |
