Belimo ZG-JSA-3 Jackshaft Adaptor

The Belimo ZG-JSA-3 Jackshaft Adaptor is a precision-engineered accessory designed to facilitate the installation of direct-coupled actuators onto 1.05-inch diameter jackshafts. When field conditions involve oversized shafts that exceed standard actuator clamp capacities, this adaptor provides the necessary mechanical interface to ensure slip-free torque transmission. Built from high-grade materials to withstand the rigors of heavy-duty HVAC damper control, the ZG-JSA-3 maintains alignment integrity, preventing binding and premature actuator wear. This component is essential for technicians retrofitting legacy systems or installing new commercial HVAC air handling units where standard mounting hardware is insufficient. By extending the compatibility of the Belimo AM, GM, and GK series actuators, it allows for seamless integration into complex building automation systems (BAS). Its robust construction ensures reliable operation in high-torque applications, providing a stable platform for precise airflow regulation and energy-efficient mechanical performance in demanding environments.

• Specifically engineered for 1.05-inch jackshaft diameters to ensure a secure, high-torque fit.
• Compatible with Belimo AM, GM, and GK actuators, streamlining field installations.
• Rugged construction prevents mechanical slippage and ensures consistent damper positioning.
• Simplifies actuator retrofitting on non-standard shaft sizes without requiring extensive modifications.
• Reduces installation downtime by providing a reliable, standardized mounting solution for large-scale air handlers.

What is the maximum shaft diameter for the ZG-JSA-3?
The ZG-JSA-3 is specifically designed to adapt actuators to a 1.05-inch diameter jackshaft, ensuring proper clamp force and alignment.

Which Belimo actuators are compatible with the ZG-JSA-3 adaptor?
This adaptor is primarily used with high-torque AM, GM, and GK series direct-coupled actuators to manage large damper loads.

Does this adaptor prevent actuator binding during operation?
Yes, by providing a precise fit for 1.05-inch shafts, it maintains the necessary concentricity to prevent side-loading and mechanical binding in VAV systems and air handlers.
