Duff-Norton manufactures screw jacks (mechanical actuators), linear actuators, ball
screw actuators, electromechanical actuators, machine screw actuators, rotary unions
(rotating joints), and air jacks. A mechanical actuator is a device used to apply
a force, push and pull, or move to a position and hold by mechanically converting
rotary motion into linear motion. Screw Jacks come in several variations: machine
screw, ball screw, micro-miniature and high duty cycle. The Duff-Norton line of
screwjacks (mechanical actuators) includes mechanical actuators (machine screw and
ball screw) ranging in size from 1/4 ton to 350 tons, stainless steel machine screw
actuators, micro-miniature actuators, high duty cycle actuators, motorized machine
screw and ball screw actuators, electric cylinders and motor control systems. Accessories
include miter gear boxes, c-face motor adapters, limit switches, transducers, visual
and digital position indicators, couplings, ball screws and ball screw systems,
and locking rings. Screw Jacks are also used for raising and lowering maintenance
platforms, opening and closing air dampers, oven doors and sluice gates, and adjusting
tooling machine beds, cable tension and workplace tables. In addition to the broad
range of applications and industries for mechanical actuators, they are also used
as alternatives to hydraulic and pneumatic systems. |

Duff-Norton manufactures electric actuators, mechanical actuators (screw jacks),
linear actuators, ball screw actuators, machine screw actuators, electric cylinders,
rollerscrews, rotary unions (rotating joints), and air jacks. Electric Linear Actuator
Products include TracMaster and LinearMaster Actuators, Packaged Controls, Modular
Actuators and PowerMaster Motor Cylinders and Synchro Cylinders. This Duff-Norton
product line of actuators features load capacities ranging from 100 pounds to 100
Tons, gear or belt drives, acme screw and ball screw systems with various AC and
DC input voltages. Packaged Controls operate the extend and retract function of
the electric actuator and are available for all Duff-Norton TracMaster and LinearMaster
Electric Linear Actuators. Duff-Norton Electromechanical Actuation Products are
specially designed for a variety of commercial and industrial applications. These
actuators are used for opening and closing, tilting and pivoting, lifting and lowering
and positioning. Applications include gates, dampers, oven and processing tank doors,
antennas, orthopedic tables and other medical equipment, ergonomic furniture, and
agricultural equipment, etc. Custom design is also available for special applications.
Electric linear actuators are now being used in place of pneumatics and hydraulics
when high maintenance and environmental problems (leaking hydraulic oil) are a concern. |
Duff-Norton manufactures SuperCylinder™ electric cylinders, mechanical actuators(screw
jacks), linear actuators, ball screw and machine screw actuators, electromechanical
