Ball Screw Actuators (Imperial) Duff-Norton

Duff-Norton Ball Screw actuators come in many standard models, or can be custom designed for any application up to 50 tons.

For select 75 ton or 100 ton applications, Duff-Norton does have the ability to provide ball screw actuators as well. Please contact our customer service department for more details.

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.

Ball Screw Actuator Performance Specifications (Imperial)
Performance Table Instructions
When reviewing any Duff-Norton Actuator Performance Specifications Table, as part of the process of selecting the best-suited actuator for your application, there are several important worm-gear ratios to consider.
Standard Ratio - is frequently chosen when higher speeds and efficiency ratings are desired.
Optional Ratio(s) - is frequently chosen when the application requires higher lifting capacities, lower speeds, or to ease the use of a handwheel.
