800 - 60,000 Nm (and above) / Idle rotation overload coupling

Idle rotation overload coupling (load-separating) with flange type

The overload coupling KTR-SI FRE is an idle rotation safety coupling with flange type to connect toothed belt pulleys or sprockets.

Our idle rotation overload coupling (load-separating) with flange type can be combined with our ROTEX jaw couplings, GEARex all-steel gear couplings or RADEX-N steel laminae couplings. Special versions of this overload coupling (e. g. flange-to-flange) are available on request.

Applications of our idle rotation overload coupling KTR-SI FRE (safety coupling):

  • Shredders (recycling)
  • Rolling mills (steel industry)
  • Extruder drives
  • Test bench technology
  • General heavy-duty drives


  • idle rotation overload coupling

  • hardened surfaces

  • maintenance-free

  • precision ±15 %

  • corrosion-protected
