70250?22010?043 Forward Main Rotor Control Link Assembly – Sikorsky H?60/S?70 Swashplate?to?Blade Pitch Rod

Description

The 70250?22010?043 Forward Main Rotor Control Link Assembly is a precision?engineered flight?control rod used on Sikorsky H?60 and S?70 series helicopters. This linkage transmits mechanical inputs from the swashplate to the main rotor pitch horns, enabling accurate blade pitch changes essential for lift generation, maneuvering, and overall rotor stability. Manufactured from high?strength alloys with corrosion?resistant rod ends and spherical bearings, it is designed to withstand continuous cyclic loading, vibration, and tensile forces encountered during demanding helicopter operations. The assembly includes adjustable end fittings to ensure proper alignment, preload, and smooth control response throughout the aircraft’s flight envelope.
