Product Description

Mechanical Actuator – Duff-Norton manufactures mechanical actuators (screw jacks), 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. Mechanical Actuators 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. Mechanical actuators 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.

Electromechanical Actuator - Duff-Norton manufactures electromechanical actuators, mechanical actuators (screw jacks), linear actuators, ball screw actuators, machine screw actuators, electric cylinders, rotary unions (rotating joints), and air jacks. Electromechanical 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 actuator and are available for all Duff-Norton TracMaster and LinearMaster Electromechanical 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. Electromechanical linear actuators are now being used in place of pneumatics and hydraulics when high maintenance and environmental problems (leaking hydraulic oil) are a concern.

Rotary Union - Duff-Norton manufactures rotary unions, rotary joints, rotating joints and offers a line of 32 series ranging up to 10,000 psi and up to 5000 RPM. Rotary Union® is Duff-Norton’s registered trademark for rotating joints. Rotating joints are used to transfer fluids from a stationary supply to a rotating component, i.e., a drum or roll. They are used in process industries like paper, printing, rubber and plastics, textile and chemical; on cranes, on machine tools and in a host of other applications. They are used to provide heating or cooling media like steam, hot oil, water or coolant to control the surface temperature of a drum or roll, to transfer air or hydraulic fluid to moving components or to add fluids to mixers while in motion. Duff-Norton has traditionally served the markets where it supplies its general purpose joints, such as the rubber and plastics industries, and in the textile market it supplies its 8000T, a joint designed especially for the textile industry. The single largest user industry of rotating joints worldwide is the pulp and paper industry, which requires large quantities of joints for steam, water and hot oil. The steam applications (i.e., dryer cans) are most prevalent in paper mills.
