Producto n° 6494
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.
Ball Screw Actuators (Inch)
Duff-Norton Ball Screw actuators come in many standard models, or can be custom designed for any application up to 50 tons.
Duff-Norton Ball Screw actuators provide high efficiency and high speed in one linear positioning package. The positive action of the low friction ball screw and nut design provides longer life at load and requires less power to achieve a specified thrust. Ball screw actuators can be used individually, in tandem or as part of a larger mechanical system. With lifts up to 20 feet, Duff-Norton Ball Screw actuators offer the perfect solution to many linear positioning applications.
Anti-Rotation Models available - contact our customer service personnel for more information Move loads and apply force more efficiently than other mechanical actuators Require less power by providing positive mechanical action Permit faster operation and longer life under load Long predictable ball screw and ball nut life Handles full load in tension or compression
