Modular Rotating Machine Screw Linear Actuators (AC)
Features & Benefits
- Integral 56 frame, C-face mounting flange.
- Three-piece flexible coupling for easy motor assembly (included).
- Four threaded holes in base for standard hydraulic cylinder, clevis end accessory attachment. Tapped 1/2 20 UNF-2B.
- Rolled thread lifting screw, with work hardened finish, reduces coefficient of friction between screw and lifting nut. Provides smooth, efficient operation and long service.
- Steel worm and bronze gear set for quiet operation. Available in 5:1 and 20:1 ratios.
- Rugged, lightweight aluminum housing is corrosion resistant.
- Bronze lifting nut for longer life.
- Standard grease fitting on housing for easy lubrication of worm gear.
- Stop-pin at end of lifting screw prevents inadvertent run-off of lifting nut.
- Rated loads from 2,000 lbs., depending on actuator gear ratio and motor horsepower
- Lifting speeds to 170 in./min. (varied with load and hp/rpm of motor)
- Standard travel up to 24 inches. (consult Duff-Norton engineering for longer travel options)
MODULAR ACTUATORS allow use in a wide range of applications by matching standard actuator models with AC or DC electric, air, hydraulic or explosion-proof drive units. The rotating screw models, featuring a traveling lift nut, permit reliable load positioning in locations which are relatively free of dust, dirt and moisture. Translating tube units, with an enclosed lifting screw and translating tube, are specified when environmental contamination is anticipated. Optional limit switches and transducers are also available for both actuator types.
