Product Description

 

Extra Thin Type Ceramic Deep Groove Balls Bearing In Material Of Silicon Carbide

 

Description of Silicon carbide ball bearing:

 

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.

 

Key properties of SSiC (Pressureless sintered silicon caride)

 

♦ 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)
