0 - 13,400 Nm / torsionally flexible, fail-safe shaft coupling

The torsionally flexible POLY-NORM ADR-SBA is a shaft coupling combined with a brake disk. The POLY-NORM type ADR-SBA is used for holding brakes.

For combinations of shaft couplings with a brake disk observe the potentially resulting high circumferential speed - KTR recommends dynamic balancing with high-speed drives from 30 m/s. The brake disk 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-SBA coupling and brake disk is used wherever holding brakes are required, for example 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.
