ELPEX flexible ring coupling


Owing to its low torsional stiffness and damping property the ELPEX coupling is very well suitable for connecting machines with a considerably non-uniform torque characteristic. Types with a fail-safe device between the flexible rings ensure emergency operation if the flexible rings are destroyed. ELPEX couplings are available in 12 sizes for torques from 1,600 Nm up to 90,000 Nm.

Examples of application

Drives with periodically exciting systems, such as

  • Internal combustion engines

  • Piston compressors

  • Piston pumps

Drives subjected to high shock loads or large shaft misalignments, for example in

  • Compressors

  • Excavators

  • Shredders

Advantages of the product

  • Highly flexible coupling without circumferential backlash for large shaft misalignments

  • Suitable for high dynamic loads

  • Good damping properties

  • Available as shaft and flange coupling

  • Designs according to API 610 and API 671 available
