Belimo KH8 Universal Crank Arm

The Belimo KH8 Universal Crank Arm is a mechanical linkage part used to connect damper shafts with compatible actuator assemblies. It provides a mounting interface that allows rotary motion from the actuator to be transferred to the damper shaft for controlled air movement. In HVAC systems it is commonly used in air handling units and ventilation dampers where it links actuator output to damper operation. The crank arm is positioned at the actuator-to-damper connection point, supporting consistent motion transfer during airflow control operations in commercial and residential ventilation setups.
