Micro Miniature Actuators
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.
Duff-Norton Micro-Miniature actuators provide extreme precision in a compact package. Accurate to within .001 inch, and equipped with anti-backlash nuts to minimize vertical backlash between the screw and worm gear nut, these units are available with either balanced, or continuous dial readings for perfect positioning every time.
Standard Duff-Norton Micro-Miniature actuators come with aluminum shell caps and housings and include stainless steel worms and lifting screws.
