65003-047 – Piper Aircraft Seat Roller Inner Bushing
Available now on the Airparts.aero Marketplace.
The Piper Aircraft 65003-047 is a genuine OEM, precision-machined inner bushing specifically designed for the seat roller assemblies found in various Piper aircraft models. This component serves as a critical, replaceable wear surface within the seat adjustment mechanism. Its primary function is to provide a smooth, low-friction interface between the seat roller and its axle or mounting pin, ensuring easy and reliable fore-and-aft adjustment of the pilot or passenger seats.
Fabricated from a high-quality bearing material, likely a self-lubricating polymer or bearing bronze selected by Piper for its durability and low friction characteristics, this bushing is essential for preventing binding or excessive play in the seat track system. Maintaining the integrity of the seat adjustment mechanism is crucial for crew comfort and operational safety (ensuring proper positioning for flight controls). Using the correct, certified OEM bushing guarantees the precise fit and material properties required for smooth, long-lasting performance.
Key Features
Genuine Piper Aircraft OEM Part: Guarantees the precise dimensions, correct bearing material, and quality standards specified for the seat adjustment mechanism.
Provides Low-Friction Seat Movement: Ensures smooth and easy fore-and-aft adjustment of crew and passenger seats.
Replaceable Wear Surface: Acts as a sacrificial element, protecting the seat roller and track components from wear and damage.
Durable, Low-Friction Material: Typically manufactured from a self-lubricating polymer (like Delrin® or Nylon) or bearing bronze, chosen for minimal friction and long service life. (Material must be confirmed by OEM documentation).
Maintains Seat Mechanism Integrity: Prevents excessive free play ("slop") and binding in the seat rollers, ensuring positive locking and smooth operation.

Why Choose 65003-047?
Choosing the genuine Piper 65003-047 bushing is essential for maintaining the smooth, reliable, and safe operation of the aircraft seats. Worn seat roller bushings can lead to difficulty in adjusting the seat, excessive play, or even jamming of the mechanism, which can be distracting or problematic during critical phases of flight. The OEM part guarantees the correct low-friction material and precise dimensions required for a proper fit and long service life. Using a non-certified bushing risks premature wear, binding, or failure, compromising comfort and potentially safety.
The 65003-047 bushing functions as a plain bearing, likely operating in a dry-running or boundary lubrication regime. If made from a self-lubricating polymer like Acetal (Delrin®) or Nylon, its performance relies on the material's inherently low coefficient of friction and good wear resistance. These polymers transfer a microscopic film onto the mating pin, creating a low-shear interface. If made from bearing bronze (e.g., SAE 660), it relies on the principles previously described (boundary lubrication via lead smearing and grease retention). The choice between polymer and bronze often depends on the specific load, speed (though seat adjustment is low speed), and environmental factors of the application. The press-fit installation is critical to prevent the bushing from rotating within the roller, ensuring wear occurs only on the intended inner bearing surface against the axle pin.
Note: This component contributes to the proper function and locking of pilot/passenger seats. Worn bushings can cause excessive seat movement or difficulty in adjustment. Bushings are wear items and are typically replaced when seat play becomes excessive or adjustment becomes difficult. Installation usually requires pressing the old bushing out and pressing the new one in using appropriate tools to avoid damaging the roller or the bushing. Ensure correct orientation if the bushing is shouldered or asymmetrical. Installation should be performed by a certified A&P mechanic.
