Duff-Norton is an ISO 9001 certified leading manufacturer of reliable and high-quality rotary unions, acme and ball screws and nuts, linear actuators, screw jacks, electric cylinders and rail maintenance equipment. These products are ideal for applications in healthcare, metal fabrication, construction, packaging, food & beverage, material handling and transportation industries. Duff-Norton Rotary Union catalogue comprises DWA, 5000, 8000 and 9000 Series rotary unions. The 9000 Series rotary unions are suitable for use with water, steam and hot oils and can withstand up to 250 psi pressure. They feature NPT connection, carbon steel or stainless steel construction and a bellows sealing system. The heavy-duty Duff-Norton ball screw actuators are mainly designed to create linear motion without friction. They include a ball recirculator, ball screw nut and ball screw spindle, available in aluminium / cast iron housing and in different power and efficiency ratings. The brand offers a wide range of these actuators and other company products, such as acme flanges and rotary union cartridges.
Duff-Norton screw jacks & linear actuators are suitable for courier shipment & air freight. They require simple packaging, depending upon the product dimensions.
Duff-Norton smart linear actuators combine intelligent solutions with robust machinery to allow simple installation, configuration and operation, allowing systems to be up and running quickly and reliably. Smart actuators are easier to set up, operate, adjust, troubleshoot and monitor by incorporating intelligent capabilities, such as those available from a variable frequency drive (VFD) or electronic programmable limit switches (EPLS).
Screw jacks from Duff-Norton are used to lift, position (push, pull, tilt and roll) and support a wide range of loads. They are ideal for plastics machinery, beverage bottling systems, aircraft assembly and paper manufacturing. Screw jacks range in size from mini screw jacks that can support up to 1000 pounds to acme screw jacks that can support up to 350 tonnes and everything in between.
It is critical to mount the actuator to avoid side loading and eccentric loading. A clevis mount actuator should be able to pivot freely on its clevis pins. There should be no brackets or supports restraining the actuator housing or outer tube. The actuator should be mounted so that the load is applied along the longitudinal axis of the translating tube, thereby improving the actuator's performance and life.
