Product Information

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. Duff-Norton ball screw actuators are available in two types: translating screw and rotating screw, each available with either upright or inverted screw. In the translating screw type, the ball nut is fixed to a rotating gear within the housing, and the lifting screw moves up and down through the nut. In the rotating screw type, the screw is fixed to the rotating gear, and the ball nut travels up and down the screw. With lifts up to 20 feet, Duff-Norton Ball Screw actuators offer the perfect solution to many linear positioning applications.
