Mechanical Screw Actuator
Duff-Norton manufactures mechanical actuators (screw jacks), linear actuators, ball screw actuators, electromechanical actuators, machine screw actuators, rollerscrews, rotary unions (rotating joints), and air jacks. A mechanical actuator is a device used to apply a force, push and pull, or move to a position and hold by mechanically converting rotary motion into linear motion. Mechanical Actuators come in several variations: machine screw, ball screw, micro-miniature and high duty cycle. The Duff-Norton line of screwjacks (mechanical actuators) includes mechanical actuators (machine screw and ball screw) ranging in size from 1/4 ton to 350 tons, stainless steel machine screw actuators, micro-miniature actuators, high duty cycle actuators, motorized machine screw and ball screw actuators, electric cylinders and motor control systems. Accessories include miter gear boxes, c-face motor adapters, limit switches, transducers, visual and digital position indicators, couplings, ball screws and ball screw systems, and locking rings. Mechanical actuators are also used for raising and lowering maintenance platforms, opening and closing air dampers, oven doors and sluice gates, and adjusting tooling machine beds, cable tension and workplace tables. In addition to the broad range of applications and industries for mechanical actuators, they are also used as alternatives to hydraulic and pneumatic systems.
Machine Screw Actuators (Inch)
Duff-Norton offers a complete line of both standard and custom engineered machine screw actuators for applications up to 350 tons.
Machine screw actuators offer positive mechanical action, precise positioning, and uniform lifting speeds. Standard configurations include upright or inverted units with translating or rotating lifting screws, and top plate, threaded, or clevis ends.
Precise Positioning - can be controlled accurately for positioning within thousandths of one inch Self Locking – models featuring higher gear ratios are inherently load holding as long as the actuator is not subject to vibration
Uniform Lifting Speeds – since many actuators feature the same gear ratios different capacities can be used in the same application to lift unevenly distributed loads with uniform speeds Quick, Sure Operation – All actuators are designed and built to be positive acting, for accurate response to motive power
