Double-Pitch Roller Chain For Transmission
Double-pitch chain whose pitch is doubled compared to standard roller chain. Since it is using the same parts as standard roller chains except for link plate, the strength remains the same and the number of parts are reduced to the half of that of standard chains, which achieves weight and cost reductions. This roller chain is best suited for relative long power transmission at lowspeed.
