Honeywell 26025B Crank Arm

The Honeywell 26025B is a professional-grade damper crank arm engineered for demanding commercial and industrial HVACR mechanical linkages. This heavy-duty component features a 3/8-inch shaft diameter and a total length of 5 3/4 inches, providing the necessary leverage for precise air volume control. Built to withstand the constant torque requirements of modulating systems, the Honeywell 26025B ensures a slip-free connection between the actuator and the damper shaft. This specific model is functionally identical to the 26025B/U, making it a direct replacement in existing pneumatic or electric drive assemblies without needing field modifications. It is commonly utilized with Honeywell MP516A and MP909D/E/H pneumatic damper actuators to regulate multi-blade dampers. The integrated elongated slot is scaled for standard 40, 50, 60, 75, and 90-degree rotations, allowing technicians to fine-tune the damper linkage stroke for optimal linear airflow performance and system efficiency.

• Universal Compatibility: Seamlessly replaces 26025B/U models and integrates with Honeywell MP516 and MP909 series actuators.
• Precision Control: The elongated slot design supports variable stroke angles (40? to 90?) for accurate modulating damper positioning.
• Industrial Durability: Machined for 3/8-inch shafts to prevent rounded edges or slippage under high-torque commercial ventilation loads.
• Optimized Leverage: The 5 3/4-inch length provides the mechanical advantage required for large-scale multi-blade damper banks.

Is the Honeywell 26025B compatible with 3/8" round shafts?
Yes, this crank arm is specifically designed with a 3/8-inch diameter bore for secure mounting on 3/8" damper axles and actuator shafts.

What is the difference between the 26025B and the 26025B/U?
There is no functional difference. The "U" suffix typically denotes "universal" or retail packaging, but the technical specifications and performance of the 26025B and 26025B/U are identical.

Can this crank arm be used with pneumatic actuators?
Absolutely. The Honeywell 26025B is the primary linkage component for MP516A and MP909 series pneumatic damper motors used in legacy and modern air handling units.
