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.

Double pitch roller chains – powerful performance
Double pitch hollow pin roller chains are normally only available in a version with straight plates as a bush or roller chain. One of the main advantages here is that the longer pitch allows transport rollers to be fitted, which significantly reduces friction and tensile forces within the chain in many applications.
Double pitch roller chains are used in conveyor technology, general engineering and plant construction, agricultural machinery, the food industry and in sorting plants. Versions with small rollers and transport rollers are available for applications requiring particularly gentle conveying.
