McFarlane MS20664C-4 Cable End Ball is a precision single-shank swage terminal designed for aircraft wire rope assemblies requiring a compact and secure ball-end attachment. Manufactured to MS20664C military specifications, this terminal is swaged onto compatible aircraft control cable to provide a permanent, high-strength connection for flight control and other cable-operated systems.

The single-shank ball design allows the cable assembly to engage with compatible sockets, retainers, pulleys, and control mechanisms where smooth articulation and reliable load transfer are essential. Once properly installed using approved swaging equipment, the terminal delivers consistent mechanical performance while resisting vibration and cyclic loading encountered during normal aircraft operation.

Constructed from high-strength corrosion-resistant steel, the MS20664C-4 is designed for long service life in demanding aerospace environments. The -4 dash size is intended for use with 1/8-inch nominal aircraft wire rope, providing a minimum breaking strength appropriate for approved aviation applications.

Routine maintenance should include inspection of the swaged connection, ball surface, and surrounding hardware for wear, corrosion, deformation, or damage. Any compromised terminal should be replaced in accordance with approved maintenance procedures to maintain continued airworthiness.
