Our Special Material Bearings are engineered for demanding environments where standard steel bearings cannot meet performance requirements. By using advanced materials such as stainless steel, ceramic (ZrO₂ / Si₃N₄), and hybrid structures, these bearings deliver superior resistance to corrosion, heat, wear, and electrical conductivity issues.
Stainless steel bearings are ideal for wet, corrosive, or hygienic environments, while ceramic and hybrid ceramic bearings offer ultra-low friction, high-speed capability, and excellent electrical insulation. These advanced material options significantly extend service life and improve operational stability in critical applications.
We provide both standard models and fully customized solutions based on customer drawings, including deep groove ball bearings, angular contact bearings, roller bearings, and thin section designs.
