Engineered for precision and reliability, the Diamond American Standard Roller Chain Spare (D08D01) is ideal for compact machinery and light-duty power transmission systems. With a pitch of 12.70 mm (1/2″) and a narrow width between inner plates of 6.25 mm (1/4″), it is well-suited for applications requiring tight tolerances and consistent performance.

This chain spare part features a roller diameter of 7.77 mm and bearing pin diameter of 3.60 mm, offering smooth articulation and reduced friction. The plate height (9.55 mm inner, 8.26 mm outer) and plate thickness of 1.25 mm on both sides ensure adequate strength while maintaining a lightweight design at just 0.43 kg per metre.

With a minimum tensile strength of 680 Kgf and a projected bearing area of 0.33 sq.cm, the D08D01 is built to handle everyday mechanical loads while extending chain life and reducing maintenance needs. Ideal for equipment in packaging, light automation, and material handling systems.
