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.
