Overview - EN 6098:2019 (Aerospace rod-ends, inch series)

EN 6098:2019 is a European aerospace standard that defines rod‑ends with spherical plain bearings (inch series) made from corrosion resisting steel with an extra wide inner ring and an external threaded shank. It applies to adjustable rod‑ends that combine a metal‑to‑metal spherical plain bearing (per EN 6097) and a threaded rod‑end body (optionally with a longitudinal groove for locking). These components are intended for use in fixed or moving parts of aircraft structures and control mechanisms.

Key topics and technical requirements

• Scope and configuration
  • Covers geometry, dimensions, tolerances and mass (figures and Tables 1–2) for the inch series.
  • Specifies extra wide inner ring bearings per EN 6097 and rod‑end bodies with external UNJ/rolled threads.
• Materials and hardness
  • Inner and outer rings: see EN 6097 (corrosion resisting steel).
  • Rod‑end body: material per SAE AMS 5643, hardness typically 35 ≤ HRC ≤ 42.
• Surface treatment and roughness
  • Acceptable finishes: passivation (ISO 8074) or cadmium plating & chromating per EN 2133 (thickness ranges noted).
  • Surface roughness requirements are specified (measured before treatment).
• Threads and groove options
  • Threads per aerospace thread standards (ISO 3161 / rolled thread standards ISO 3353).
  • Optional longitudinal groove (toomer locking) per NAS 559 convention.
• Loads, clearance and testing
  • Static axial/radial and fatigue loads defined in Table 4 (axial proof, ultimate radial, fatigue spectra).
  • Clearance classes (normal/reduced) and verification methods per EN 6099.
  • Annex A: verification of fatigue loads and standard fatigue spectrum.
• Marking, designation and quality
  • Rules for designation, marking (EN 2424) and quality management requirements included.

Practical applications and users

• Who uses EN 6098:2019
  • Aerospace designers and stress engineers specifying rod‑ends for airframe and flight control linkages.
  • Manufacturers of aerospace rod‑ends and spherical plain bearings.
  • Procurement, quality and certification teams verifying compliance for aircraft components.
• Typical applications
  • Control surface linkages, actuator attachments, landing gear mechanisms and other moving or fixed structural joints where corrosion resistance, controlled dimensions and predictable fatigue performance are critical.
