Belimo KH12 Universal Crankarm 3/4" X 1" DIA

The Belimo KH12 Universal Crankarm is a mechanical linkage component connected to actuator output shafts to valve or damper shaft in HVAC systems. It has a 3/4" bore on one side and a 1" diameter shaft on the other which offers a secure way to transmit motion when used in air handlers and boilers. The actuator and driven shaft are clamped by the crankarm, which is in turn mounted on a setscrew or connector. This connection contributes to smooth and accurate system operation by ensuring proper movement through component connections, assisting in precise control valves and dampers.
