Overview
EN 2498:1990 is a CEN aerospace standard that defines the characteristics, dimensions and loads for adjustable rod ends incorporating a self-aligning plain bearing with self-lubricating liner and a threaded shank. Adopted nationally (e.g., SIST EN 2498:2001), the standard covers assemblies intended for flight control rods and other aerospace structural rods, and specifies intended service temperature limits from -55°C to +150°C. The rod end design includes a self-aligning ball bearing per EN 2501 and a rod end body featuring a circumferential identification groove and an optional longitudinal groove for locking.
Key Topics
- Scope and application: Defines which adjustable rod ends are covered (self-aligning bearing + self-lubricating liner + threaded shank) and their aerospace use.
- Component definition: Clarifies that the bearing element is the self-aligning ball bearing described in EN 2501 and describes the rod end body features.
- Identification features: Requirement for a circumferential groove to identify location and an optional longitudinal groove for locking.
- Dimensions and loads: Establishes the dimensional parameters and load capacities applicable to these rod ends (specific dimensions/loads are set in the standard itself).
- Environmental performance: Service temperature range specified as -55°C to +150°C, reflecting typical aerospace operational extremes.
- Design intent: Focus on adjustable, self-aligning components suitable for flight control systems and structural linkages where alignment and lubrication reliability are critical.
Applications
Who uses EN 2498:1990 and why:
- Aerospace designers and engineers selecting rod ends for flight controls, actuators, linkages and structural rods.
- Manufacturers producing thread-shank rod ends with self-lubricating liners to meet aerospace dimensional and load requirements.
- Procurement and quality teams ensuring purchased rod ends conform to recognized aerospace standards for interchangeability and safety.
- Maintenance and overhaul organizations verifying replacement parts and ensuring compatibility with aircraft system specifications.
Practical benefits:
- Ensures interchangeability and predictable mechanical performance of rod ends in flight control and structural applications.
- Reduces risk of misalignment and lubrication failures by specifying self-aligning, self-lubricating bearing systems.
- Supports design compliance with aerospace environmental and load demands.
Related Standards
- EN 2501 - referenced for the self-aligning ball bearing with self-lubricating liner used in EN 2498 rod ends.
- National adoptions/editions (e.g., SIST EN 2498:2001) reflect the standard’s implementation in local regulatory frameworks.
