Our sprocket plates with pilot bore meet strict European (EN) standards for precision, durability, and seamless alignment in industrial power transmission, conveyors, and machinery. Built for versatility, they offer customization, premium materials, and advanced processing—all backed by rigorous quality checks.
Customizable Design: Tailor to your specs with client-approved drawings; choose from multi-standards (ANSI, DIN, JIS, BS, plus brands like SATI/MARTIN).
Premium Materials: Steels (C45, SS304/316, 40Cr, Q235(S235JR), Q345, C20, 20CrMnTi,42CrMn,), engineering plastics (POM, PA6), Brass(Copper), and cast iron—matched to your application.
Enhanced Performance: Advanced heat treatment (hardened teeth, carburizing, gas nitriding) and surface finishes (black oxide, nickel/chromium plating) for wear/corrosion resistance.
Rigorous Quality: 100% inspection at every stage ensures reliability and minimal downtime.
