Features & Benefits
– Integral housing flange engineered for NEMA 56 frame motor. C-face mounting.
(NEMA 42 and 48 and IEC71 frame motor C-face mounting options available).
– Rated loads to 8896N, depending on actuator gear ratio and motor horsepower.
– Lift speeds to 4318mm per minute (varied with load and kw/rpm of motor).
– Standard travel up to 608mm. (consult Duff Norton Australia for longer travel options).
– Can be tandem-coupled for synchronous operation.
– Optional motors, limit switches and position indicating transducer.
– Clevis attachment accessories available for mounting eye bracket, clevis bracket and pivot pin.
(ROTATING MACHINE SCREW MODELS)
– Integral 56 frame, C-face mounting flange or IEC71.
– 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.
(TRANSLATING TUBE MACHINE SCREW MODELS)
– Outer aluminum tube is corrosion-resistant and protects translating tube, lifting screw and nut.
– Wiper-scraper seal in end of outer tube keeps dirt out and lubricants in.
– Bronze guide bushing inside of outer tube reduces lateral movement of translating screw.
– Translating tube zinc coated for weather-resistance.
– Single or double lead lifting screw and nut for high efficiency and long wear.
– Vent in outer tube prevents pressure build-up in the actuator
– Furnished with standard clevis end on translating tube.
– Threaded end is available; and on special order, depending on application, any type of threaded
connection may be substituted.
(ROTATING BALL SCREW MODELS)
– 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.
– Ball-bearing type screw and mating nut with rolling contact reduces friction to a minimum providing
capability for higher speed and longer life with less power requirement.
– 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.
(TRANSLATING TUBE BALL SCREW MODELS)
– Outer aluminum tube is corrosion-resistant and protects translating tube, lifting screw and nut.
– Wiper-scraper seal in end of outer tube keeps dirt out and lubricants in.
– Bronze guide bushing inside of outer tube reduces lateral movement of translating screw.
– Translating tube zinc coated for weather-resistance.
– Single or quadruple lead ball-bearing type lifting screw and nut for higher efficiency and long life.
– Vent in outer tube prevents pressure build-up in the actuator
– Furnished with standard clevis end on translating tube. Threaded end is available; and on special
order, depending on application, any type of threaded connection may be substituted.
