Belimo ZG-NM4 Crankarm Kit

The Belimo ZG-NM4 Crankarm Kit is a specialized damper actuator accessory engineered for NM Series actuators when direct coupling to the damper shaft is physically obstructed or impossible. Functioning as a high-performance HVAC linkage kit, the ZG-NM4 provides a reliable mechanical interface for crankarm mounting in space-constrained installations or retrofit applications. This kit serves as the direct replacement for ZG-NM3, offering improved fitment and long-term durability for existing damper motor linkage setups. For contractors managing external actuator mounting, this kit ensures precise torque transmission and consistent 90-degree rotation control. Its robust construction minimizes mechanical play, which is critical for maintaining accurate air regulation in commercial HVAC systems. Whether you are performing a field-fabricated installation or replacing legacy Honeywell-style drive systems, the ZG-NM4 is the standard for Belimo crankarm adaptor reliability in the field.

• Universal Compatibility: Specifically designed for seamless integration with Belimo NM series actuators.
• Retrofit Ready: Provides an efficient ZG-NM3 replacement path for older systems without requiring extensive modifications.
• Precision Control: Enables crankarm rotation in tight quarters where direct shaft mounting is restricted.
• Durable Construction: Built with industrial-grade materials to withstand the high-torque demands of HVAC damper control.
• Installation Flexibility: Ideal for field-fabricated mounting plates and complex actuator linkage configurations.

• Is the ZG-NM4 compatible with older NM actuators? Yes, it is the direct successor to the ZG-NM3 and maintains the same mounting footprint for Belimo linkage hardware.
• Can this kit be used for Honeywell actuator replacements? Yes, the ZG-NM4 is frequently used by technicians as a crankarm adaptor kit to adapt modern Belimo actuators to legacy Honeywell mounting configurations.
• When should I use a crankarm kit instead of direct coupling? Use the ZG-NM4 when the damper shaft is inaccessible or when the space between the duct and surrounding obstacles is too narrow for the actuator body.
