The Duff-Norton SuperCylinder(TM) adds a precision guided translating tube system to proven Duff-Norton mechanical actuator components to provide a clevis mounted actuator line with broad capabilities. Features include speeds of up to 136 in/min, capacities up to 25 tons, standard strokes up to 13 ft, special aluminum bronze worm gears, ball screw or acme screw, and clevis mounting. A ground and chrome plated translating tube sliding in polymeric bearings produces excellent wear resistance. This guided tube assembly lets SuperCylinders achieve much greater stroke lengths in compressive loading than is possible with conventional double clevis mounted mechanical actuators.
