ROTEX® padrão

0 - 35,000 Nm / torsionally flexible jaw coupling

The original - renowned industrial standard

The torsionally flexible jaw coupling ROTEX Standard is an elastomer coupling with feather keyway and particularly low-priced due to its simple structure.
For mounting the hubs of the elastomer coupling are simply pushed on the shafts and axially fastened via setscrews.

Our flexible elastomer coupling ROTEX Standard is provided with splines acc. to DIN and SAE as a standard.

The torsionally flexible ROTEX couplings are suitable for universal use and applied as a flexible shaft connection in almost all ranges of general mechanical and plant engineering.


  • torsionally flexible coupling for torsional vibration-damping power transmission

  • low-cost standard type

  • standard spiders made of high temperature-resistant T-PUR

  • splines acc. to DIN and SAE

  • complying with ATEX (acc. to EU directive 2014/34/EU)
