|Material||Silicon Carbide Ceramic|
Silicon Carbide Bearing is made of silicon carbide ceramic that has the advantages of lightweight and high corrosion resistance. Stanford Advanced Materials (SAM) is a trusted supplier and manufacturer of high-quality sintered SiC, reaction bonded SiC, and recrystallized SiC. We provide high-quality Silicon Carbide Bearing with high purity at competitive prices. Customization is available upon request.
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.
