Ceramic rings are high-performance structural ceramic components. We craft them from premium advanced materials: alumina, ジルコニア, silicon carbide and silicon nitride. They provide excellent wear resistance, high mechanical strength, corrosion resistance and thermal stability. They serve as bearings, spacers, seals and support rings in industrial machinery, automotive systems, chemical equipment, energy applications and semiconductor devices. We supply ceramic rings in various sizes, materials and specifications. We also offer custom design and precision machining for specialized demands.
