This heavy-duty crankarm is a vital hardware component for HVAC actuator systems, designed to provide a secure and reliable connection between the actuator and mechanical linkage. Precision-engineered to fit a 3/4-inch shaft, this part is essential for converting rotary motion into the linear force needed to operate air dampers, louvers, and ventilation valves. Commonly used in commercial air handling units and industrial climate control systems, it ensures smooth, precise adjustments to airflow. Built for durability and long-term performance, this crankarm is a key replacement part for maintaining high-efficiency ventilation and heating systems that utilize AFB series actuators.
Our team is happy to help you verify compatibility before you order. We'll confirm it fits your specific furnace model.
