Schneider Electric (Barber Colman) AM-112 Crank Arm

The Schneider Electric (Barber Colman) AM-112 Crank Arm is a critical linkage component designed for industrial HVAC damper control and actuator assemblies. Engineered for precision, this 3/8 inch crank arm facilitates the mechanical connection between the actuator drive shaft and the damper linkage, ensuring accurate air volume control and sequences. Specifically designed to fit 3/8" diameter damper shafts or splined actuator shafts, the AM-112 is a direct replacement for maintenance and new installations where a damper linkage crank arm is required. The high-quality zinc plated finish provides essential corrosion resistance, making it suitable for demanding commercial environments and mechanical rooms where humidity or chemical exposure is a factor. For field technicians and contractors, this part ensures a secure, slip-free interface required for precise positioning of ventilation dampers. Integrating the AM-112 into your control system maintains the mechanical integrity and operational efficiency of the entire air handling unit.

• Universal Compatibility: Optimized for standard 3/8" damper shafts and splined actuator shafts common in Barber Colman and Schneider Electric systems.
• Enhanced Durability: Zinc plated steel construction prevents oxidation and mechanical wear in rigorous HVAC environments.
• Reliable Linkage: Provides a robust connection point for actuator linkages, reducing the risk of slippage during high-torque operations.
• Streamlined Installation: Compact design allows for easy integration into tight damper housings and mechanical assemblies.

What shaft size is the AM-112 compatible with?
The AM-112 is specifically engineered for 3/8 inch (0.375") diameter damper shafts or splined actuator shafts. Ensure your shaft O.D. matches these specs before installation.

Can this crank arm be used with other actuator brands?
While designed by Schneider Electric for the Barber Colman line, it is compatible with any 3/8" splined or round shaft that accepts standard HVAC crank arm linkages.

Is the AM-112 suitable for outdoor air dampers?
Yes, the zinc plating provides the necessary protection against moisture and corrosion typical in outdoor air intake or exhaust damper applications.
