Company History

History of Duff-Norton Europe

Duff-Norton Europe — previously known as Raccords Gautier or S.E.R.G. — was founded in 1927.

At that time, the company supplied rotary unions for the tire manufacturing industry. It has expanded progressively since then, first on the French market and subsequently on a European and global level.

In 1998, Columbus McKinnon Corporation, headquartered in Amherst in the state of New York, acquired Raccords Gautier, a move that signaled a commitment to grow together on the basis of a mutually enhancing product range.

Raccords Gautier proved to be a natural fit for Duff-Norton, a subsidiary of Columbus McKinnon and manufacturer of the Rotary Unions® brand.

A joining of forces
Bringing these two companies together has allowed us to offer our customers an extensive range of rotary unions that comprehensively meet requirements across a variety of sectors, such as the following:

  • Automotive
  • Petrochemical
  • Machine tools
  • Food
  • Pharmaceutical
  • Textile
  • Paper
  • Printing
  • Etc.

Rotary unions are mechanical devices that allow one or more fluids to be transferred between a fixed part and a rotating part while maintaining a perfect seal between the two parts. We offer numerous types of rotary union in order to fulfill our customers’ every requirement.

Rotary unions can transfer one or more fluids at the same time, at different pressures and temperatures.

Rotary unions manufactured by Duff-Norton Europe allow fluids to be transferred at 0–700 bar (up to 1,500 bar for custom products) while maintaining oscillating movements and rotational speeds of up to 5,000 rpm.

Our rotary unions are available in nickel-plated steel (with corrosion resistance) or in stainless steel; alternatively, they can be manufactured in any other material according to your needs.
