GORGEOUS CERAMICS (GGS) specializes in manufacturing high-performance silicon nitride ceramic disks, custom-processing silicon nitride ceramic components for extreme operating conditions that offer robust mechanical properties, thermal shock resistance, and wear resistance.
GORGEOUS CERAMICS (GGS) supplies wear-resistant bearing discs for motor bearing assemblies to numerous high-speed motor manufacturers. Unlike traditional steel components, which are prone to overheating and wear during high-speed operation, thus affecting equipment lifespan, ceramic discs’ ultra-high strength effectively reduces bearing operating temperature, decreases wear and vibration, improves motor operating efficiency, and extends equipment lifespan.
We can customize silicon nitride ceramic disks of various diameters, thicknesses, surface finishes, and complex geometries according to customer drawings and technical requirements.
