Silicon carbide is an ideal material for bearings. It has good corrosion resistance, great mechanical strength under high temperature and excellent wear resistance. Nextgen Advanced Materials supplies Silicon Carbide Bearing with high quality and fast delivery. Customization is also available.
Nextgen Advanced Materials supplies Silicon Carbide Bearing with high quality and fast delivery. 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 excellent ceramic material for applications requiring good erosion and abrasive resistance. Consequently, it is useful in a variety of applications including spray nozzles, shot blast nozzles and cyclone components.
Silicon carbide is an ideal material for sealing rings and bearings. The SiC bearing has good corrosion resistance, great mechanical strength under high temperature and excellent wear resistance. We can supply ring and bearing products made by SiC as well as other SiC parts.
