0 - 13,400 Nm / Shaft coupling with brake drum

The torsionally flexible POLY-NORM ADR-BTA is a shaft coupling system-related provided with a brake drum. The POLY-NORM type ADR-BTA is used as a holding brake.

For combinations of shaft couplings with a brake drum observe the potentially resulting high circumferential speed - KTR recommends dynamic balancing with high-speed drives from 30 m/s. The brake drum is positioned on the driven side where the highest mass moment of inertia is effective.

Applications of our torsionally flexible, fail-safe shaft coupling with brake drum (drum brake):
This combination of POLY-NORM ADR-BTA coupling and brake is used, as an example, on conveyor belts and generators. Applications with moderate demands can be combined with POLY-NORM GJL hubs.

Shaft coupling and brake by KTR:
The customer benefits from being supplied from 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.
