A coupling, in simplest terms, is a device that connects different objects together. Couplings do much more than that, however, in myriad applications in many industries. They connect so that the motion of one object can be transmitted to the other directly or differentially, and this can be done through electrical, hydraulic, or – in the case of Nordex – mechanical means.
Simply defined, a coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. The coupling has been around since shortly after the invention of the wheel, i.e.—no wheel, no coupling. And something that has been around even longer than that is the often harsh and extreme environments in which couplings are at times required to function. Considering the seemingly endless list of coupling applications—from mining to the space station—it’s a given that couplings are often subjected to, among other things, extreme heat, cold, sand and degraded lubrication.
Charles Paulsen, associate director of the Mechanical and Manufacturing Technologies for Energy and Sustainability (MET2) program at the Connecticut College of Technology walked into the Nordex lobby in Brookfield, CT, on a mission. He was visiting engineering companies in the area hoping to find people interested in supporting a student project known as Prosthetics for Kids.
“The prosthetic arm created by the students was for children who were either born without an arm, lost their arm in an accident or in an act of terror in other countries,” said Lisa Barrett, sales manager at Nordex, Inc.
Nordex was excited to participate in the project because it mirrored the company’s very own engineering philosophy:
“We exist to assist fellow engineers design and bring to life new and innovative ideas,” said Barrett. “Our goal is to make a difference in the world by offering innovative ideas and fostering the philosophy that anything is possible.”
Nordex contributed parts for the Prosthetics for Kids project. Recently Senior Engineer Nick Antonelli and Barrett visited students at the University of Hartford where eight student projects were presented as part of the MET2 program.

During my morning scan of the headlines, I noticed an article about prosthetic devices that are powered by a person’s own brain. In fact, these types of prostheses are the culmination of research and practical prototype building stretching back for decades. It’s very rewarding to know that Nordex was involved in fabricating prototype components for some of the scientists who developed brain-wave driven prosthetics.
Sometime around 1990, we received a phone call from an engineer at one of the top-tier institutes of technology asking us if we would be willing to help them build a special gear box. My answer is always “yes,” depending on the size of it (cannot be bigger than a breadbox). This gear box involved high torque, but had to be very lightweight.
The active compliance end-effector, or ACE, is a robot designed for teleoperated or robot-assisted ultrasound diagnostic imaging. ACE provides parallel motion, 6 degrees of freedom and haptic force feedback. The movements of ACE are similar to a Stewart platform. Developed by Vivonics with products supplied from Nordex, Inc.
A state of the art, global headquarters was custom designed and constructed to support company operations and accommodate our continued expansion. This location has become a world-class design and manufacturing center for support and communication with engineers anywhere. Included in the design of this facility is an extensive Class 100 clean room. By combining electro-mechanical technical expertise with clean room capabilities, we now perform Manufacturing Systems Integration for semiconductor and analytical equipment, as well as precision machining, gear design and production. Our System Integration capabilities are made possible through strict adherence with ISO 9001, verified by Det Norske Veritas. DNV, a world recognized leader in ISO registration and compliance performs bi-annual audits.
Our manufacturing and cultural diversity enable Nordex to deliver solutions that enhance our customers’ goals, allowing us both to achieve new heights! The Nordex Design Guide is available free of charge. In it, you will find the building blocks of machines and instruments found from the depths of the ocean floor, to the reaches of outer space.
Spur gears are manufactured in several styles and materials, including 303 Stainless Steel, 2024-T4-Alumnium anodized before cutting, and nonmetallic materials with a twenty degree pressure angle and varying sizes of pitch, face and bore. Nordex offers hubless, pin hub, or split hub spur gears in precision quality Q10, Q12, Q14.
With a pitch range of 1/10 to 120. Additionally Nordex offers an extensive range in sizes to choose from. Custom gears will be manufactured. Nordex also manufactures Anti backlash Gears, Cluster Hub Gears, Helical Gears, Internal Gears and Miter and Bevel Gears. Continue reading
Nordex, incorporated in 1960, designed and manufactured surface mount technology assembly equipment. In 1975, the product line was modified for the manufacture of miniature precision electro-mechanical parts and assemblies. Today, over 25 years later, our focus is on fully integrated turnkey subsystems for medical, laboratory and industrial analytical instruments, factory automation, and the semi-conductor OEM industries.
