The S1823-3 is an aircraft nose gear steering rod end used in Cessna light aircraft landing gear systems. It is a precision spherical rod end (heims joint) that connects the nose gear steering linkage to the nose wheel assembly, allowing controlled angular movement while transmitting steering forces.

This component is part of the nose landing gear (NLG) steering system and is designed to handle cyclic loads, vibration, and shock forces during taxi, takeoff, and landing operations.

It is commonly specified in Cessna IPC (Illustrated Parts Catalog) applications and must be matched exactly by thread size, geometry, and load rating for airworthiness compliance.

Key features include:

Aircraft-grade rod end bearing for nose gear steering
Used in Cessna nose landing gear (NLG) steering linkage
Precision spherical bearing for angular movement
Threaded external rod end (3/8-24 configuration)
Designed for high-load vibration and shock environments
Steel construction with corrosion-resistant finish (variant dependent)
Enables smooth steering articulation of nose wheel assembly
Installed in certified aircraft maintenance and overhaul procedures
Controlled OEM part number (S-series airframe hardware)
Must be matched exactly to IPC specifications (not generic substitute)
Common in Cessna 150/152/172-series nose gear systems depending on configuration
