Belimo ZG-AFB Adaptor Kit

The Belimo ZG-AFB Adaptor Kit is a specialized mounting accessory engineered for short shaft linkage applications, specifically designed to bridge the gap between AFB and NFB actuator series and existing damper hardware. This kit is essential for contractors performing retrofits or repairs where the standard actuator drive may not align with legacy crank arm setups. The hardware ensures high-torque transmission without slippage, maintaining damper actuator compatibility in demanding HVAC environments. By utilizing heavy-gauge steel components, the ZG-AFB provides a rigid connection point for crank arm linkages, allowing for precise 1/2" to 1.05" diameter shaft adjustment. This HVAC actuator mounting kit eliminates the need for field-fabricated brackets, ensuring that the Belimo replacement parts meet OEM tolerances for stroke alignment and rotational force. For technicians managing commercial damper repair, this kit facilitates a clean installation when standard direct-coupled mounting is obstructed by mechanical interference.

• Engineered for AFB/NFB Series: Purpose-built to match the mounting footprint and torque requirements of AF and NF spring-return actuators.
• Precision Linkage Alignment: Simplifies the synchronization between the actuator drive and the damper crank arm to prevent binding.
• Rugged Construction: Zinc-plated steel components resist corrosion and mechanical fatigue in high-cycle airflow applications.
• Universal Shaft Clearance: Designed to accommodate varying shaft lengths, providing flexibility in tight mechanical rooms.
• Retrofit Efficiency: Reduces labor time during damper drive replacement by utilizing existing linkage rods and ball joints.

Will this kit work with older AF or NF series actuators?
The ZG-AFB is specifically optimized for the newer AFB and NFB versions. While the footprints are similar, verify the shaft dimensions and mounting hole patterns before attempting to retrofit legacy non-B series units.

What is included in the ZG-AFB adaptor kit?
The kit typically includes the crank arm adaptor, necessary mounting bolts, and hardware required to secure the actuator to a flat surface or bracket for linkage-driven operation.

Can I use this for direct-coupled mounting?
No, this kit is designed specifically for applications where the actuator cannot be mounted directly onto the damper shaft and requires a remote linkage configuration.
