Double-Pitch Roller Chain For Transmission
Double-pitch roller chain features a pitch that is twice that of standard roller chains, making it suitable for long-distance transmission applications. By using the same components as standard chains except for the link plates, it maintains equivalent strength while reducing the number of parts by half, resulting in lower weight and cost. It is particularly ideal for low-speed power transmission over relatively long distances.

- Connecting link for the A2080 is split pin type.
- Sprocket: For chains with teeth No. 29T (with 14 1/2 working teeth) or smaller, use the exclusively designed sprockets for double-pitch roller chains.
- For chains with teeth No. 30T (with 15 working teeth) or larger, use KCM standard sprockets.
