General Information
Overview
EN 4539-2:2019 (Part 2: Inch series) is a European aerospace standard that defines the dimensions, loads and characteristics of wide-series spherical plain bearings made of corrosion resisting steel with a self-lubricating liner. It covers bearings designed for elevated loads under low oscillations and intended for use in aerospace and defence applications over the temperature range −55 °C to 163 °C. This part specifies the inch-series sizes and related technical data for design, procurement and quality control.
Key topics and requirements
- Scope & configuration: Wide-series spherical plain bearings (inch series) with and without swaging grooves; dimensions expressed in millimetres after surface treatment.
- Materials:
- Inner ring: steel per EN 2030, hardened to 55–62 HRC.
- Outer ring: steel per EN 3161, hardness 28–37 HRC before swaging.
- Liner: self-lubricating, low-friction, wear-resistant material meeting EN 4540 requirements.
- Performance parameters: Tables give permissible static and dynamic loads, starting torques, and projected surface area for duty-cycle calculations (duty cycles defined in EN 4540). Example size data and load ratings are provided for codes 03–32.
- Dimensional tolerances & surface finish: Tolerances use definitions in ISO 1132-1; surface roughness values are specified before surface treatment.
- Design notes: Swaging grooves can reduce push-out loads; attention is drawn to potential indentation of mountings by inner-ring bearing faces.
- Marking & designation: Marking follows EN 2424 (style A); technology codes (A = bonded liner, B = injected/moulded liner) are used in designation.
- Quality & certification: Manufacturers must operate an approved aerospace production organisation and maintain a QA system such as EN 9100; qualification procedures per EN 9133 are recommended.
Applications
- Use cases: control linkages, actuator pivots, landing gear attachments, flight control mechanisms and other aerospace components requiring rotational articulation under elevated static loads with low-frequency oscillation.
- Who uses it: aerospace designers, component manufacturers, procurement/specification engineers, quality managers, and maintenance/repair organisations specifying or validating spherical plain bearings for airframe and rotorcraft assemblies.
