All SSiC Bearing 6000 Fitted With Cage Of P6/ABEC3 Precision
Description of All SSiC Bearing 6000 (SSiC+PTFE):
1. SSiC races and balls: Are made of highly purified, sub-micron silicon carbide material. The atmospheric pressure solid phase sintering method at a high temperature of 2250°C are used to produce SSiC (Sintering SiC), so the free silicon and free carbon in the products are close to the theoretical values and can resist corrosion by hydrofluoric acid, which is the most excellent ceramic material with the best corrosion resistance among the known materials.
2. cage: has excellent chemical stability, corrosion resistance (is one of the best corrosion resistance materials in the world today resistant to molten metal sodium and liquid fluorine, all kinds of acid and alkali and organic solvent), sealing, high lubrication, non-viscosity, electrical insulation and good anti-aging endurance, excellent temperature resistance (can work in +250℃ to -180℃ temperature for a long time). So bearings fitted with cage in material of can be used in many special working condition.
Performance advantages of All SSiC Bearing 6000 (SSiC+PTFE):
With a density and coefficient of linear expansion close to that of silicon nitride ceramic materials, high hardness Hv2250, wear resistance, resistance to various strong acids, strong alkalis, salt corrosion, high temperature resistance.
Application of All SSiC Bearing 6000 (SSiC+PTFE):
Because of its outstanding properties, SSiC Bearing 6000 are suitable for the petroleum, chemical, semiconductor, food machinery, pharmaceutical industry, etc.,.
