Belimo KH6 Universal Crank Arm

The Belimo KH6 Universal Crank Arm is a motion transfer component that connects an actuator to a damper shaft, allowing rotational movement to be delivered through a mechanical linkage. As the actuator turns, the unit pivots with the shaft and transmits the applied force to the connected linkage, producing controlled damper movement in response to control commands. It is fitted directly onto a compatible actuator shaft, where HVAC systems use coordinated linkage assemblies to regulate damper position and airflow direction. Its rigid construction ensures proper movement between linked parts, limits unnecessary mechanical play, and provides consistent motion transfer for damping control assemblies.
