Belimo KH8 Universal Crank Arm

The Belimo KH8 Universal Crank Arm is a mechanical linkage component designed to transfer rotary motion from an actuator to a connected damper shaft or control mechanism. As the actuator rotates, the crank arm converts that movement into controlled mechanical motion, allowing the attached assembly to move through its intended range. It is secured to the actuator shaft, allowing HVAC systems to transmit actuator movement properly to compatible dampers and related control assemblies. The rotary limb supports a firm mechanical connection, minimizes unwanted play between linked components, and supports precise movement of the connected mechanism during control adjustments.
