Springs in Aerospace Landing Gear: Meeting Extreme Load and Environmental Standards

Landing gear springs absorb some of the most punishing load cycles of any mechanical component in an aircraft — repeated high-impact touchdown forces, extreme temperature swings between ground and altitude, and years of service where failure is not an option. Designing and manufacturing for this environment demands more than a standard spring catalog can offer.

WHAT LANDING GEAR SPRINGS MUST WITHSTAND

• High-impact load at touchdown. Every landing cycles the spring through its full working range under sudden, high-magnitude force.
• Extreme temperature swings. Components must perform consistently from freezing high-altitude conditions to hot tarmac exposure.
• Corrosion resistance. Humidity, de-icing fluid, and runway chemicals all attack unprotected metal surfaces over an aircraft's service life.
• Certified fatigue life. Aerospace components require documented, repeatable fatigue performance — not just a one-time load test.

HOW SEYUNDA SUPPORTS AEROSPACE APPLICATIONS

• Aerospace-grade materials. Stainless steel (304/316/631) and oil-tempered steel selected for strength-to-weight and long-term reliability under cyclic load.
• Fatigue-extending finishes. Shot peening, passivation, and Geomet/DACROMET coatings to resist corrosion and extend service life.
• Tight-tolerance CNC coiling. Precision coiling and grinding to hold the consistency aerospace load specs demand, part after part.
• Documented quality systems. ISO 9001-certified processes provide the traceability aerospace supply chains require.

WHY THIS MATTERS

In aerospace, a spring failure isn't a warranty claim — it's a safety event. Partnering with a manufacturer that treats material selection, finishing, and documentation as part of the engineering conversation (not an afterthought) is what keeps a component qualified for the long haul.
