Landing Gear Bushings

Bronze bushings in aircraft landing gear must survive extreme impact loads, high cycle fatigue, vibration, and wide temperature swings—while preventing galling on hardened steel pins. Wrought and cast nickel‑aluminum bronzes are the gold standard thanks to their strength, corrosion resistance, and excellent sliding behavior with proper lubrication.

Typical applications

• Main & nose gear trunnion bushings

• Torque‑link (scissor) and drag‑brace joints

• Piston/rod‑end eye bushings and actuator clevises

• Steering collar and shimmy damper sleeves

• Axle, truck beam, and door‑hinge bushings

Why it matters

• Time‑on‑wing: high wear resistance and anti‑galling → longer intervals.

• Weight & cost: replaceable bushings protect expensive housings/pins.

• Reliability: stable properties across temperature and corrosive ramp/runway environments.
