Schneider Electric (Barber Colman) AM-753 Mounting Clamp

The Schneider Electric (Barber Colman) AM-753 is a heavy-duty shaft mounting clamp kit engineered specifically for HVAC damper actuators. For professional mechanical contractors, this universal mounting clamp is the critical solution for secure actuator attachment when working with larger damper shafts that exceed standard 1/2-inch capacities. This kit includes two precision-manufactured clamps designed to provide maximum grip and torque transfer without slippage, ensuring reliable long-term operation of the damper assembly.

The AM-753 is compatible with a wide range of DuraDrive series actuators, including the Mx40-717x and MS40-634x units. Its versatile design accommodates 5/8-inch square shafts as well as 3/4-inch to 1-inch round shafts. To ensure optimal performance and avoid equipment stress, technicians should utilize a 1/2-inch socket wrench to apply the recommended 4 to 6 ft-lbs of torque to the mounting nuts. This Schneider Electric accessory is essential for maintaining the alignment and structural integrity of direct-coupled actuator installations in demanding commercial environments.

• Universal Compatibility: Fits both 5/8" square shafts and 3/4" to 1" round shafts, reducing the need for multiple specialized parts.
• Enhanced Torque Transfer: Dual-clamp configuration ensures a high-friction grip for high-torque spring and non-spring return actuators.
• Direct Replacement: Designed as a direct OEM fit for Schneider Electric and Barber Colman control systems.
• Durable Construction: Built to withstand the constant cycling and vibration of industrial HVAC air handling units.

Which actuators are compatible with the AM-753?
This mounting clamp is specifically designed for the Schneider Electric Mx40-717x and MF40-6343 series, as well as several MS40 and MS50 damper actuators. It is the standard requirement for any application where the damper shaft diameter exceeds 1/2 inch.

Does the kit include both clamps?
Yes, each AM-753 package contains two universal mounting clamp assemblies. Both must be used simultaneously to prevent shaft misalignment or damage to the actuator drive mechanism.

What tool is required for installation?
A standard 1/2-inch socket or crescent wrench is required to tighten the nuts. For proper seating, technicians should ensure the actuator is perpendicular to the shaft before final torquing.
