Overview
EN 2585:2019 defines the characteristics, configuration and requirements for spherical plain bearings made from corrosion-resisting steel with a self-lubricating liner. This standard covers the wide series intended for elevated loads at ambient temperature, for use in fixed or moving parts of aircraft structures and control mechanisms. Bearings covered by EN 2585:2019 are suitable for operation in the temperature range −55°C to +163°C and are supplied with or without swaging grooves depending on installation needs.
Key Topics
The standard specifies practical and prescriptive items necessary for design, procurement and quality control:
- Configuration and dimensions: nominal sizes, tolerances and mass are provided (see figures and tables in the standard).
- Surface roughness and surface treatment: roughness values (before treatment) and inner-ring surface treatments (e.g. chromium plating or passivation) are referenced.
- Loads and starting torques: permissible static and dynamic loads and starting torque ranges are tabulated to support selection for specific load cycles.
- Materials and hardness:
- Inner ring: steel per EN 2030, 55 HRC to 62 HRC.
- Outer ring: steel per EN 3161, 28 HRC to 37 HRC (before swaging).
- Liner: self-lubricating, low-friction, wear-resistant material complying with EN 2755.
- Design variants: bearings may be supplied with or without swaging grooves; note that push-out loads can be reduced when swaging grooves are present.
- Designation and marking: product designation rules and marking requirements follow EN 2424 (style A) and the standard's designation scheme.
- Quality management: manufacturers must operate an approved aerospace production organization and maintain an aerospace-accepted quality management system (e.g., EN 9100).
Applications
EN 2585:2019 bearings are specified for aerospace applications where robust, corrosion-resistant articulating joints are required. Typical uses include:
- Structural joints in airframes and control linkages
- Pivot points in landing gear subassemblies and actuation systems
- Control mechanism bearings where maintenance-free or reduced-lubrication operation is desired
Benefits for engineers and procurement teams:
- Clear dimensional and load data to match bearing selection to service loads
- Material and surface-treatment prescriptions that support corrosion resistance and wear performance
- Defined marking and designation for traceability in aerospace supply chains
Related Standards
EN 2585:2019 references and aligns with other aerospace standards and technical specifications, including:
- EN 2755 - Technical specification for these bearings
- EN 2030, EN 3161 - Material specifications for inner/outer rings
- EN 2132 - Electrodeposition of chromium
- EN 2424 - Marking of aerospace products
- ISO 8075 - Surface treatment of hardenable stainless steel
- EN 9100 / EN 9133 - Aerospace quality management requirements
