Duff-Norton manufacture SuperCylinder electric cylinders, mechanical actuators (screw jacks), linear actuators, ball screw and machine screw actuators, electromechanical actuators, rollerscrews, rotary unions (rotating joints), and air jacks.

Duff-Norton offer a range of high capacity electric cylinders. From 2 tons to 25 tons, users can choose from clevis or trunnion mounting; offset, right angle, parallel, in-line mounting; standard or stainless steel housings, with speeds ranging up to 380 inches per minute.

Duff-Norton electric actuation products, available from PT Link Systems , are designed for a variety of commercial and industrial applications. These actuators are used for opening and closing, tilting and pivoting, lifting or lowering and positioning. Applications include gates, dampers, oven and processing tank doors, antennas, orthopaedic tables and other medical equipment, ergonomic furniture, and agricultural equipment.

Custom designs are also available for special applications. Electromechanical linear actuators are now used as an alternative to pneumatics and hydraulics when high maintenance and environmental problems (leaking hydraulic oil) are a concern.

Duff-Norton offer the new SCN series SuperCylinders in addition to the SCW series. The SCN series combines the ball screw driven translating tube system with trunnion mounted, high efficiency helical or helical-bevel and oil filled gearboxes. The SCW series combines a ball screw or ACME screw driven translating tube system with existing clevis mounted worm gear actuators. Both Duff-Norton SuperCylinder series use a precision guided translating tube system to broaden application capabilities.

A ground and chrome plated translating tube sliding in polymeric bearings produces better resistance to buckling. This lets SuperCylinders achieve higher stroke lengths, making them an alternative to double clevis mounted mechanical actuators. Enclosure of the screw by the tube system shields SuperCylinders from environmental contaminants and retains lubricants, requiring less maintenance and allowing longer service. SuperCylinders use hydraulic cylinder grade wiper seals to exclude dirt from the screw area. The modular concept employed by Duff-Norton for both SCN and SCW series SuperCylinders allows a number of configuration possibilities for tailoring of SuperCylinders to an application.

There is a wide selection of gear ratios. This choice of ratios allows precise tailoring of the actuator speed and load specifications. Several additional motor and ratio options are available to meet specific capacity, speed, or life requirements.
