{"product_id":"121-394","title":"121-394","description":"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.\u003cbr\u003e\nType: HVAC Actuator Crankarm\u003cbr\u003e\nSize: 3\/4 Inch Shaft\u003cbr\u003e\nApplication: Ideal for commercial heating, ventilation, and air conditioning (HVAC) systems, specifically for air damper control and actuator linkage assemblies in air handlers and rooftop units.\u003cbr\u003e\nSpecifications: Designed for 3\/4-inch diameter shafts; compatible with AFB series rotary actuators; high-strength construction for industrial-grade torque requirements.","brand":"BCFurnace","offers":[{"title":"CRANKARM,3\/4IN SHAFT,BELIMO,AFB \/ 121-394","offer_id":50217065120029,"sku":null,"price":259.67,"currency_code":"CAD","in_stock":true},{"title":"CRANKARM,3\/4IN SHAFT,BELIMO,AFB \/ S1-02927105000","offer_id":50217065152797,"sku":null,"price":259.67,"currency_code":"CAD","in_stock":true}],"url":"https:\/\/bcfurnace.myshopify.com\/products\/121-394","provider":"BCFurnace","version":"1.0","type":"link"}
