0 - 12,500 Nm / torsionally flexible jaw coupling with brake drum

The torsionally flexible jaw coupling ROTEX BTAN is an elastomer coupling combined with a brake drum. ROTEX type BTAN is used as a holding brake, but also a a service brake.

The ROTEX jaw coupling with brake drum (drum brake) to be mounted to external drum brakes with double shoes. The brake drum is positioned on the driven side. For combinations with a brake drum please note the potentially resulting high circumferential speed - KTR recommends dynamic balancing with high-speed drives from 30 m/s.

Safety-relevant drives are preferably combined with hubs made of steel/GJS, applications with moderate demands can be combined with GJL hubs.


  • each coupling type can be combined with various sizes of brake drums

  • following DIN 15431/15435

  • axial plug-in

  • damping vibrations

  • compensating for displacements (axial, radial, angular)
