Overview - EN 2790:1991 (CEN)
EN 2790:1991 is a CEN aerospace standard that defines the characteristics, dimensions and load capabilities for adjustable rod ends used on aircraft flight control rods. The standard covers rod ends that combine a self-aligning plain bearing with a self-lubricating liner (EN 2501) and a threaded shank with an engagement depth of 1.5 × thread diameter. These components are specified for service in temperatures from −55 °C to +150 °C and are intended for critical aerospace structural control applications.
Key topics and technical requirements
- Component configuration
- Adjustable rod end assembly composed of a self-aligning ball/ plain bearing with self-lubricating liner (per EN 2501) and a rod end body with threaded shank.
- Threaded shank engagement
- Specified engagement length: 1.5 × thread diameter - used to ensure reliable mechanical engagement in flight control linkages.
- Identification and locking features
- Circumferential groove on the shank to identify engagement depth.
- Optional longitudinal groove for mechanical locking where required.
- Dimensions and loads
- Standard provides dimensional data and load ratings for the specified rod-end types (see full standard for tables and limits).
- Operating environment
- Rated for use across the aerospace temperature band −55 °C to +150 °C.
- Reference
- Directly references EN 2501 for the self-lubricating liner specification.
Applications and who uses EN 2790
- Primary use: Flight control rods and linkages in aircraft structures where adjustable, self-aligning joints are required.
- Typical users
- Aerospace design engineers specifying control-system hardware.
- Manufacturers and suppliers of rod ends and aircraft hardware.
- Procurement and quality assurance teams verifying compliance for flight-critical components.
- Maintenance and overhaul organizations selecting replacement rod ends for service.
- Benefits
- Ensures interchangeability, predictable mechanical performance, and appropriate identification/locking options for flight-critical rod-end assemblies.
Related standards
- EN 2501 - Specification for the self-lubricating liner used in the self-aligning plain bearing.
- Other aerospace series standards covering rod-end variants and materials (see CEN catalogue for related EN aerospace documents).
This summary helps engineers, procurement specialists and suppliers quickly understand the scope and practical use of EN 2790:1991 when specifying or sourcing adjustable rod ends for aerospace flight control applications.
