About this product
The A2528225320300 is an aircraft‑grade coil spring manufactured from corrosion‑resistant stainless steel. Engineered for precision load‑deflection characteristics and long cycle life, it delivers consistent force in vibration‑damped assemblies and mechanical linkages across extreme temperature ranges. Supplied with EASA Form 1 trace paperwork, it meets stringent airworthiness requirements.

PRODUCT DESCRIPTION

A2528225320300

  • Stainless Steel Alloy: Resists corrosion from moisture, hydraulic fluids, and cleaning solvents.

  • High Cycle Life: Rated for over 100,000 compression cycles without significant set or fatigue.

  • Vibration Damping: Steel spring steel filament provides inherent damping in dynamic systems.

  • Surface Treatment: Passivated finish prevents fretting and extends service life.


  • Provides return force in retract/extend cylinders during gear cycling.

  • Maintains contact pressure in wing‑flap mechanism guides under aerodynamic loads.

  • Delivers tactile resistance and centering in engine‑throttle control levers.

  • Ensures quick, positive return of rudder‑brake pedals in flight‑deck assemblies.


  • Is any lubrication required?

No lubrication needed. The passivated finish resists corrosion and fretting.

  • How many cycles is it rated for?

Tested to over 100,000 compression cycles with less than 5 % loss in load.

  • How do I inspect for end‑of‑life or fatigue?

Measure free height and load at a given deflection. Replace if the spring rate drops by more than 10 % or if you observe corrosion or cracking.
