Double pitch roller chains

Apart from their pitch, double pitch roller chains are constructed on the same basis as single pitch chains in accordance with ISO 606 and meet the same standard specifications in terms of their dimensions. Unlike short pitch chains constructed to standard ISO 606, these chains are intended for use in conditions that place less demand on chain speed and power transmission. The principle difference is that the plates of double pitch roller chains are twice the length of the plates fitted to standard roller chains. Chains from the range constructed to the American Standard include versions with normal plate thickness or thicker plates, as well as variants with smaller or larger rollers.
