Material：Made from high-strength stainless steel or alloy steel materials, providing excellent hardness, wear resistance, and long-term durability for precision applications. Structural Shape：The component features a slender shaft structure combined with a hexagonal positioning end, ensuring stable installation and precise rotational support. Size Range：Total length: 7– 100 mm, shaft diameter (spindle): Φ6 – Φ12 mm, flange diameter: Φ1 – Φ25 mm. Internal Design：Designed with a solid integrated structure to enhance mechanical strength, improve concentricity, and maintain stable operation during high-speed movement. Surface Treatment：The surface is finely polished and electroplated to achieve a smooth metallic appearance while improving corrosion resistance and reducing friction wear. Manufacturing Process：Produced through high-precision CNC turning and grinding processes, ensuring tight tolerances, consistent quality, and excellent assembly compatibility.
