6000 Silicon Carbide Ball Bearings Fitted With PEEK Cage CSQ
Silicon Carbide Balls Bearing 6000 Fitted With PEEK Cage
Description of Silicon Carbide Balls Bearing 6000:
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. PEEK cage: Our company adopted PEEK material for the crown structure cage, which have light body and high strength. PEEK material has similar corrosion resistance to ceramic materials, and has a good resistance to radiation, self-lubricating properties, a high degree of wear resistance and other characteristics.
Material advantages of SSiC (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.
