The SDF gear couplings are double engagement Gear Couplings manufactured with two flanged sleeves with internal spur gear teeth, connected with a set of heat treated alloy steel fasteners and meshed with accurately matched, machined and ground crown toothed hubs.
The closely controlled quality of the gearing profile contributes to minimum end float to obtain the best possible alignment.
