Ceramic Angular Contact Balls Bearings In Material Of SSiC
Description of SSiC Ceramic Angular Contact Balls Bearings:
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.Because of the excellent properties of silicon carbide material, 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.
