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.

Fields of application of our torsionally flexible jaw coupling ROTEX BTAN with brake drum (drum brake):
This combination of coupling and brake is used wherever holding brakes or service brakes are required, e. g. on conveyor belts, generators, turbine drives, industrial fans, cranes, hoists, etc.
Safety-relevant drives are preferably combined with ROTEX hubs made of steel/GJS. Applications with moderate demands can be combined with GJL hubs.

Couplings and brakes by KTR:
The customer benefits from being supplied by one single source with the option to develop the brakes (KTR-STOP or EMB-STOP) as well. The KTR-STOP brake is hydraulically actuated and EMB-STOP is electromechanically actuated.


  • 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)
