Belimo KH10 Crankarm

The Belimo KH10 Crankarm is a heavy-duty mechanical accessory designed for precision damper linkage applications. This universal crankarm is engineered from galvanized steel to provide a robust connection between the actuator and the damper shaft, ensuring reliable torque transfer in commercial HVACR systems. Specifically built for high-demand environments, the KH10 features a clamping range that accommodates damper shafts from 9/16" up to 1.05" (14 to 25 mm) in diameter. With a standardized slot width of 8.2 mm (21/64"), it is fully compatible with KG10A ball joints, allowing technicians to create custom push-rod configurations when direct-coupling is not an option. This component is essential for Belimo actuator accessories kits, supporting GK, GM, SM, and EF series actuators. Its zinc-plated finish prevents corrosion, maintaining structural integrity in mechanical rooms and rooftop units. Whether you are performing a damper actuator retrofit or a new installation, the KH10 ensures a secure, non-slip grip on various shaft profiles, including round and square geometries.

• Universal Compatibility: Fits a wide range of damper shafts from 9/16" to 1.05", reducing the need for multiple stocked parts.
• Durable Construction: Fabricated from galvanized steel to resist oxidation and withstand high-torque HVAC requirements.
• Precise Linkage: Designed with an 8.2 mm slot width to integrate seamlessly with HVAC ball joints for linear-to-rotary motion conversion.
• Versatile Application: Ideal for actuator mounting in tight spaces where direct-coupled installation is physically restricted.

• What shaft sizes does the KH10 support? It handles any damper shaft diameter between 14 mm and 25 mm (9/16" to 1.05").
• Can this crankarm be used with any ball joint? It is specifically optimized for the KG10A ball joint to ensure a proper mechanical fit and zero-slop operation.
• In what scenarios should I use a crankarm instead of direct coupling? Use the KH10 when the actuator cannot be mounted directly on the shaft due to clearance issues or when multiple dampers must be linked to a single HVAC actuator.
