Pneumatic torque limiter

Safety couplings FHW-P

The FHW-P is controlled by an air connection that runs through the drive shaft. The disengaging torque is controlled via the air pressure. Complete decoupling is also possible.

Disengagement torque from 0 to 400 Nm

Shaft diameter up to 50 mm

Pneumatic connection through shaft, maintenance-free
