Monitoring and Diagnostic Services




Kop-Flex® and Jaure® can help you recognize significant savings in these applications:


  • Hot mills
  • Cold mills
  • Edger drives
  • Bridle rolls
  • Levelers



Unfortunately, no mechanical product can last forever and couplings are no exception. While Kop-Flex® and Jaure® products are designed and built to last, many applications are so severe that rapid wear and/or coupling damage may occur. Kop-Flex® and Jaure® have the largest and most experienced engineering staff in the industry, with an arsenal of modern analysis tools at our disposal including FEA, and a staff dedicated to coupling service. Let our technical experts provide recommendations on how to help prevent coupling problems and premature drive train failures.

  • Real-Time drive train monitoring
  • Repair and refurbishment
  • Expert failure analysis
  • Cost savings through consultation
  • Field technical support





  • Alloy steel nitrided and carburized gearing
  • CGG™ - carburized and ground gearing
  • Custom-designed for your application





  • Industry standard DIN and SAE flanges

  • Elastomeric element available in various compounds and harnesses























The emergence of high strength steels has reduced rolling mill drive train reliability due to the increased rolling forces required to process these new products.  Reducing the peak torques and vibratory torques are one approach to prolong the life of drive train components and can be accomplished by altering the system torsional dynamics. Kop-Flex® and Jaure® torque monitoring services can demonstrate how to model the dynamic torsional response, normalize the model with empirical data, and evaluate the effectiveness of increased damping and stiffness changes.  These analyses have led to the successful implementation of design changes at several mills, increasing drive train reliability and providing means to establish more precise maintenance intervals.
