Belimo KH6 Crankarm

The Belimo KH6 Universal Crankarm is a heavy-duty mechanical accessory engineered for precise linkage in damper applications. Constructed from high-quality galvanized steel, this damper crank arm is specifically designed to interface with KG6 ball joints, providing a robust solution when direct-coupling an actuator is not feasible. With a fixed slot width of 6.2 mm (1/4"), the KH6 offers the necessary versatility for HVAC mechanical linkage, fitting damper shafts ranging from 3/8" to 11/16" in diameter or 3/8" to 9/16" square. Field-tested for durability, it ensures linear-to-rotary motion transfer without excessive play, maintaining the integrity of your damper actuator accessories suite. Whether you are performing a retrofit or a new installation, this industrial-grade component provides the leverage and physical stability required for long-term air handling control.

• Universal Compatibility: Fits both round and square damper shafts, reducing the need to carry multiple specialized stock items.
• Durable Construction: Zinc-plated galvanized steel provides significant corrosion resistance in demanding mechanical rooms.
• Precise Fit: Specifically machined for KG6 ball joints to eliminate mechanical slop and ensure accurate positioning.
• Fail-Safe Integration: Ideal for use with LF and TF series actuators where remote mounting is required to clear obstructions.

Which ball joint is compatible with the KH6?
The KH6 is specifically designed for use with the KG6 ball joint. For larger requirements, the KH8 crankarm would be paired with the KG8 or KG10A joints.

Can this be mounted on a square shaft?
Yes, the universal clamping design accommodates square shafts between 3/8" and 9/16", as well as standard round shafts up to 11/16".

What is the primary application for this crank arm?
It is primarily used in damper shaft linkage setups where the actuator must be mounted away from the damper shaft using a mounting bracket and linkage rod.
