70550?02102?056 Main Rotor Pitch Control Link Assembly – Sikorsky H?60/S?70 Cyclic?Collective Flight?Control Rod

Description

The 70550?02102?056 Main Rotor Pitch Control Link Assembly is a precision?engineered flight?control rod used on Sikorsky H?60 and S?70 series helicopters. This linkage transmits swashplate?driven cyclic and collective inputs to the main rotor pitch horns, enabling accurate blade pitch adjustments 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. Adjustable end fittings ensure proper alignment, preload, and smooth control response throughout the aircraft’s flight envelope.
