These have a stroke of 0.50 m (19.7 in) for shorter, less powerful conveyors, and 1 m (39.4 in) for long faces or conveyors with extremely high installed power. These allow control of 1 m (39.4 in) and 2 m (78.7 in) of slack chain respectively. An automated system keeps the AFC chain at optimum tension during operation.
