General Information
Overview
EN 6097:2019 - Aerospace series: Spherical plain bearing, metal-to-metal, extra wide inner ring in corrosion-resisting steel (inch series) - specifies inch‑based dimensions and loads for metal-to-metal spherical plain bearings intended for aircraft structures and control mechanisms. The standard defines geometry, tolerances, materials, surface treatments, load ratings and marking/identification rules for bearings with extra wide inner rings and either inner- or outer-ring slide‑hole treatments.
Key topics and technical requirements
- Scope & configuration: Inch-series bearings with extra‑wide inner rings for fixed or moving airframe parts and control linkages. Configurations include versions with or without swaging grooves and various grease‑hole/lubrication groove arrangements (codes S, R, E, F, G).
- Dimensions & tolerances: Detailed dimensional tables and figures give bore/outside diameters, masses, radii and angular limits; values are presented in inches (with mm equivalents), and surface roughness in μm/μin. Dimensions apply after surface treatment.
- Materials & hardness:
- Inner ring per EN 2030 - hardness 55 ≤ HRC ≤ 62.
- Outer ring per EN 3161 - hardness 28 ≤ HRC ≤ 38 (before swaging).
- Surface treatment:
- Inner ring treatment per ISO 8075 (codes T/P).
- Outer ring cadmium plating per EN 2133 where specified (5–8 µm / 200–300 µin), often followed by chromating.
- Swaging groove & lubrication features: Defined swaging groove treatments (code R vs S) and grease-hole/lubricating groove options to support assembly and lubrication paths.
- Loads & performance: Permissible static and ultimate static radial/axial loads are specified by diameter code (see Table 2). Load definitions and test methods reference EN 2337 and TR 4475.
- Additional requirements: Surface roughness measurement before treatment, clearance, temperature range, recommended greases and solid-film lubricants, designation, marking and quality management clauses.
Practical applications
- Landing-gear linkages, actuator bearings, control‑surface hinges, pivot joints and other aircraft structure points where high‑reliability, metal‑to‑metal spherical plain bearings are required.
- Use where corrosion‑resisting stainless steels and cadmium‑plated options are needed for environmental resistance and assembly constraints.
Who should use EN 6097:2019
- Aerospace design and stress engineers specifying bearing components.
- Bearing manufacturers, heat‑treatment and plating suppliers.
- Procurement and quality managers verifying compliance, and maintenance engineers selecting replacements.
