KMC Controls VTD-0804 Ball Joint

The KMC Controls VTD-0804 is a precision-engineered swivel ball joint designed for high-performance HVAC damper linkage and actuator assemblies. Built specifically to secure a 5/16 inch OD pushrod to a crankarm, this mechanical component features a 1/4-20 male threaded mounting stud complete with a locknut for secure, vibration-resistant positioning. In commercial building automation systems, maintaining tight tolerances in mechanical linkages is critical for accurate airflow control and environmental management. This KMC VTD-0804 ensures smooth, low-friction swiveling action, reducing lateral stress on actuator shafts and preventing premature wear on damper components. Whether you are performing a field repair or a new control installation, the 1/4" X 20 ball joint provides the durability and precise articulation required for pneumatic and electronic actuation systems. As a standard in HVAC mechanical linkage parts, it facilitates the reliable transfer of torque from the driver to the damper blades, ensuring your system maintains peak operational efficiency.

• Precision Linkage: Enables smooth articulation between 5/16" pushrods and crankarms for accurate damper positioning.
• Secure Installation: Includes a 1/4-20 male mounting stud and integrated locknut to prevent loosening under mechanical load.
• Industrial Durability: Specifically manufactured for the continuous cycling demands of commercial HVAC and building automation systems.
• Universal Compatibility: Standardized threading and rod sizing make it a versatile fit for wide-ranging actuator hardware.

What rod size is compatible with the VTD-0804?
