JAURE S.A., European leader in the production of flexible couplings and transmission elements since 1958, belongs to the Power Transmission Solutions business unit of the group with the same name, and forms a tandem with the Kop-Flex firm in order to assure a global approach in providing solutions for the applications requirements in the most demanding sectors of the world couplings market.

For all the stages of STEEL PRODUCTION, JAURE SA can supply a suitable coupling to drive your equipment. With more than 100 years of combined experience in the metal industry, JAURE/KOP-FLEX provides innovative solutions in the STEEL, ALUMINIUM and COPPER INDUSTRIES.

JAURE SA supply program covers gear/elastic couplings and spindles for steel production, hot and cold rolling mills, processing lines, finishing lines for both new plants and modernization of old ones. For more information on JAURE SA products please visit JAURE SA website www.regalbeloit.com


Cranes and hoisting equipment are widely used in all stages of metals production, from general purpose cranes to the most demanding ladle cranes.

JAURE SA gear, barrel, elastic and disc pack couplings have been used in a variety of demanding crane applications for many years.

JAURE SA® TCB® barrel couplings connect the cable drum with the gearbox output shaft. They are recommended for installation in:

  • Crane lifting mechanisms
  • Winch conveyors
  • Platform hoists



A gear coupling is one of the simplest and most common types in use today. It is also one of the most difficult to design and evaluate due to the number of variables. These can include tooth design, material, and lubrication, all of which can affect its successful operation.

One of the more common applications for gear spindles is for ferrous and non-ferrous rolling mills drives. This is where technology is applied to achieve a higher product quality with lower maintenance costs.

Modern rolling mills and revamping of old mills require new developments, such as:

  • New machine design concepts
  • Superior metallurgical practices
  • Application of process control
  • Automation

j6Consequently, mechanical components including gear spindles are becoming a critical component of the drive train. JAURE designs its gear spindles to ensure performance, operating efficiency and easier maintenance.

This meets the demands of the most up-to-date mill equipment. All the above advantages are implemented by continuous development of teeth profile, surface heat treatment, materials’ quality and seals.


Kop-Flex® brand high performance disc, patented diaphragm and gear couplings satisfy a variety of demanding applications such as turbines, compressors, generators and pumps in many industries including petrochemical, refinery, power generation, gas pipeline and LNG.

In addition, Kop-Flex offers the unique POWERLIGN® torque measurement system designed to help optimize output while reducing operating and maintenance cost.

JAURE SA is a European leader in the production of flexible couplings and transmission elements. They were formed in 1958. In 2006 they became part of Power Transmission Solutions, partnering with Kop-Flex. This combination provides global solutions for applications requirements in the most demanding sectors of the world couplings market.

Products range from gear, grid, jaw, elastomer, disc, universal joints as well as almost every conceivable engineered or made-to-order coupling you require.

Kop-Flex, Browning, JAURE and Morse brand couplings not only offer the most extensive breadth of product available in the industry, but we are also to custom-design and engineer for specific applications.

Additionally, JAURE is able to troubleshoot problematic applications by applying the skill and expertise of one of the largest engineering staffs in the industry.


The primary purpose of JAURE® MT marine gear couplings is for main propulsion & maneuvering of vessels. However, they can also be used in dredging and electrical winches.

JAURE‘s scope of supply ranges from class-approved gear couplings for thruster, propeller, and water jet applications to special sealed alloy steel gear couplings for underwater operation in the dredging industry. JAURE marine gear couplings are also designed for long spams (steel and composite shafts available).

JAURE® MT Marine meets the requirements of classification societies for main propulsion & maneuvering. They are also delivered on demand with the official certificates. JAURE MT Marine is type approved by DNV.
