Johnson Controls DMPR-KC053 Crankarm

The Johnson Controls DMPR-KC053 is a precision-engineered damper crankarm designed to facilitate a robust mechanical connection between an actuator and a damper blade pin extension. Built for rigorous HVAC air management applications, this component features a 1/2-inch shaft diameter, providing secure mounting and torque transmission for standard drive shafts. The adjustable radius mechanism allows for a stroke length ranging from 1 inch to 2 3/4 inches, giving field technicians the flexibility to fine-tune mechanical linkage geometry and ensure precise damper modulation or shut-off.

Constructed with a black cadmium finish over steel, the DMPR-KC053 is designed to withstand the cyclic loads and environmental conditions typical of heavy-duty air handlers and economizer sections. This HVAC replacement part is critical for achieving the proper leverage ratio in damper actuator installations, ensuring that rotational Force is efficiently converted to linear or angular motion at the blade arm. Its compatibility with existing Johnson Controls hardware kits makes it a reliable choice for maintaining system integrity in both new builds and retrofits.

• Universal Versatility: The adjustable radius from 1 to 2 3/4 inches allows for precise throw adjustments across various damper configurations.
• Engineered Durability: Steel construction with a protective finish prevents corrosion and wear in high-cycle airflow control systems.
• Standardized Fit: Specifically machined for a 1/2-inch damper shaft, ensuring a slip-free connection for consistent performance.
• Contractor Grade: Streamlines field installations by allowing on-site modifications to linkage travel without needing multiple arm sizes.

• What size drive shaft is this compatible with? It is designed for use with a 0.5-inch (1/2") diameter drive shaft.
• Can this be used for both electric and pneumatic actuators? Yes, this crankarm is compatible with any actuator using a 1/2-inch shaft, provided the torque requirements align with the linkage geometry.
• Is the installation hardware for mounting the linkage rod included? This kit typically serves as the primary crankarm; always verify if specific U-bolts or ball joints are required for your unique linkage setup.
