ELPEX Flexible Ring Coupling
Technical information

Please enter your complete MLFB number here

  • Highly flexible, backlash-free tire coupling
  • Nominal torque range from TKN = 1,600 Nm up to 90,000 Nm with 9 sizes
  • Temperature range: from –40 °C to +80 °C

Flexible and adaptable

Owing to its low torsional stiffness and damping properties the ELPEX® coupling is very well suited to connecting machines with considerably non-uniform torque characteristics. Types with a fail-safe device between the flexible rings ensure emergency operation if the flexible rings are destroyed.

Did you know?

The ELPEX coupling’s transmission characteristics are determined essentially by the flexible rings. These flexible rings are manufactured from a natural rubber blend with a multi-ply fabric lining. They are split so that they can be changed without having to move the coupled machines.
