Overview
EN 2501:1988 (adopted as SIST EN 2501:2001) is a CEN aerospace-series standard that defines the characteristics, dimensions and load ratings for spherical plain bearings made from corrosion-resisting steel with a self-lubricating liner and a wide inner ring. The standard is intended principally for rod end fittings and specifies the usable temperature range: -55 °C to +150 °C.
Key Topics
- Bearing type and construction
- Spherical plain bearings in corrosion-resisting steel
- Integrated self-lubricating liner to reduce maintenance and improve service life
- Wide inner ring geometry for specific load and alignment requirements
- Dimensions and tolerances
- Standardised external and internal dimensions for interchangeability (as specified in the standard)
- Load characteristics
- Defined static and dynamic load capacities and relevant load conditions (bearing loads and limits)
- Operating conditions
- Specified temperature range -55 °C to +150 °C, ensuring suitability for typical aerospace environments
- Material and corrosion resistance
- Requirements for corrosion-resisting steel and compatibility with self-lubricating liners
- Application guidance
- Intended primary use in rod end fittings and other joint assemblies where spherical motion and corrosion resistance are required
Applications
EN 2501:1988 is directly applicable to aerospace designers, manufacturers and supply chains that need standardized spherical plain bearings for rod-end joints and articulating connections. Typical users include:
- Aerospace OEMs and component manufacturers specifying bearings for control linkages, actuator joints and structural rod ends
- Design and maintenance engineers who require standardised dimensions, load ratings and environmental performance
- Procurement and quality assurance teams ensuring purchased components meet aerospace interchangeability and performance requirements
- Certification bodies and inspectors verifying compliance with aerospace series bearing specifications
Related Standards
- Other aerospace-series bearing standards covering different bearing types and materials
- General bearing standards and material specifications (ISO/EN) for complementary guidance on testing, tolerances and quality control
EN 2501:1988 is a focused technical reference when selecting or specifying spherical plain bearings for corrosion-prone aerospace applications where self-lubrication, dimensional interchangeability and reliable performance across -55 °C to +150 °C are required.
