Description
The Johnson Controls D-3244-100 Crank Arm transfers motion from the actuator to connected dampers or linkage assemblies that enable controlled positioning of airflow components within the system. It works as a mechanical connection element that converts motor movement into the rotational motion required for damper operation. Within HVAC systems such as air handling units and ventilation control systems, it supports precise modulation of airflow by linking actuator output to damper blades. Included as part of the linear actuator assembly, it enables accurate movement control, maintains coordinated operation, and supports consistent system response during varying load conditions.
