Worldwide the most common running gear encountered is the American Series Roller Chain 81X. This we therefore describe as the GRAIN CHAIN. It is always 2.609” pitch (66.27 mm). As operational duty has increased with it has the demand for a heavy duty version. This has been achieved by increasing the height and thickness of the side plates, although maintaining the same gearing details. Where necessary therefore the heavier versions can be used to upgrade existing equipment. Flights are normally WT the welded version, but John King uniquely offer BT style being bent integral produced to customer standards.
