New One Ton Ball-Screw Actuator Provides Precise Linear Movement
Oct 6, 2004
  E-mail article
Printer friendly page
Charlotte, NC -- Duff Norton is introducing a new addition to its already extensive ball screw actuator line up. For load applications requiring precise, efficient linear movement the Duff Norton Ball Screw Actuator is the ideal solution.

The new one-ton capacity ball screw actuator has a standard 23.1% efficiency rating, can be driven at 0.5 maximum horsepower, and is available with Top Plate, Clevis, or Threaded End mounts.

Operation is simple. As one turns the horizontally mounted worm shaft sliding contact is made with a worm gear inside the actuator housing. The worm gear is attached to a ball nut fitted with re-circulating steel balls that makes translating contact with the ball screw reducing friction to a bare minimum and converting torque to thrust. The positive action of the low friction ball screw (which has also been heat treated for less wear) and nut design provides longer life at load and requires less power to achieve a specified thrust.

Our ball screw actuators can be used individually, in tandem, or as part of a larger mechanical system. With lifts up to 20 ft., Duff-Norton Ball Screw actuators come in many standard models, or can be custom designed for any application up to 50 tons.

Since our beginning, more than 100 years ago, Duff-Norton has earned a reputation for reliable, high quality products that meet the industrial lifting, positioning and transfer needs of our worldwide customers. Both our standard and custom designed products are subjected to the same rigorous testing throughout the design process to assure maximum performance and quality.

Our products are widely used throughout all the process and related industries such as oil & gas extraction, mining, material handling, and agriculture. Head adjustments on extrusion and injection molding machines, rolling applications (leveling, forming, pressing, and slitting), process flow adjustments, storage bin operations, conveyor height adjustments and belt adjustments, bottling machinery height adjustments, liquid vessel positioning, de-agglomeration and pulverizing applications, and many more. Should you have further questions regarding how our products are used please contact us.
