Ceramic Rings

Hunan Guoci New Material Technology Co., Ltd. (Guoci Ceramics) specializes in the manufacture and supply of a wide range of high-performance Ceramic Rings, Bushings, Washers/Gaskets, Sleeves, Seals, and Cylinders made from High-Purity Alumina(95%-99.9% Al₂O₃), Zirconia(YSZ, Mg-PSZ, Ce-TZP, ZTA), Silicon Carbide(SiC), and Silicon Nitride(Si₃N₄), which offer high temperature resistance, high strength, high hardness, high toughness, high wear resistance, and high insulation properties.

How to choose a ceramic ring material? The rationale for choosing depends on the specific function of the ring:

• Used for insulation, light load positioning, or general wear resistance? Budget is a priority? → Aluminum oxide rings are sufficient.
• Used for mechanical seals or bearings, requiring high toughness and wear resistance, but with less aggressive media? → Zirconia rings are a mainstream and cost-effective choice.
• Used for demanding mechanical seals (highly corrosive, high speeds, high pressures) or extreme wear resistance? → Silicon carbide rings are a superior solution.
• Used for the most demanding applications (high-speed bearings, severe thermal cycling, extreme lightweighting) and cost is not a concern? → Silicon nitride rings offer top-tier performance and reliability.
