Overview
EN 3288:1994 (CEN) specifies the characteristics of double-row self-aligning ball bearings in steel with cadmium plating, designated diameter series 2 for airframe rolling applications. These bearings are intended to withstand slow rotations, oscillations and swivelling under load, and are designed for installation between fixed and moving parts of aircraft structures and control mechanisms. The standard covers use over a temperature range from -54°C to 150°C and is aligned with national adoptions (e.g., SIST EN 3288:2001).
Key Topics
- Bearing type: Double-row self-aligning ball bearings in steel, cadmium plated
- Intended motion: Slow rotations, oscillations and/or swivelling under load
- Application location: Between fixed and moving aircraft structural parts and control mechanisms
- Operating temperature: Specified use from -54°C to 150°C
- Scope focus: Dimensions and loads appropriate to diameter series 2
Practical value: the standard defines essential properties to ensure interchangeability, reliable performance in low-speed dynamic conditions, and compatibility with airframe design requirements without prescribing installation-specific design modifications.
Applications
These bearings are targeted to aerospace engineers, maintenance teams, procurement specialists and airframe designers who require standardized rolling elements for structural and control interface points. Typical application benefits include:
- Consistency and interchangeability: Standardized dimensions and load criteria help ensure replacement parts fit and perform as expected.
- Safety and reliability: Defined operating temperature limits and motion conditions help specify suitable components for critical airframe joints.
- Material and corrosion control: Steel construction with cadmium plating addresses wear and corrosion considerations typical in aerospace environments.
Use cases where EN 3288:1994 guidance is especially relevant:
- Hinges and control link pivots subjected to slow oscillatory motion
- Structural rolling interfaces between fixed fittings and moving assemblies
- Maintenance and spares planning for older or legacy aircraft using diameter series 2 bearings
Related Standards
EN 3288:1994 is part of the aerospace bearing series and should be consulted alongside broader bearing and aerospace component standards, including:
- Other EN and ISO bearing standards covering single- and multi-row bearings
- Aerospace component specifications that reference bearing dimensions and environmental requirements
Consult the issuing organization (CEN) or national adoption documents (e.g., SIST EN 3288:2001) for official status, amendments, and detailed normative references.
