Silicon Carbide Bearing Description

Silicon carbide (SiC) is a lightweight ceramic material with high strength properties comparable to diamond. It has excellent thermal conductivity, low thermal expansion, and is resistant to corrosion from acids. 

Silicon carbide is an ideal material for sealing rings and bearings. It has good corrosion resistance, great mechanical strength under high temperatures, and excellent wear resistance. We can supply ring and bearing products made by SiC as well as other SiC parts.
