Aerospace series - Bearings, airframe rolling - Single row self-aligning roller bearings in steel, cadmium plated - Dimensions and loads

This standard specifies the characteristics of single row self-aligning roller bearings in steel, cadium plated, designed to withstand only slow rotations, osciliations and/or swivelling under load. They are intended for use in bell crank lever ends or at the end of rigid flightcontrol rods for transmission puropses, before or after servo operation. The airframe rolling bearings defined in this standard are used form -54°C to +150°C.

Overview

EN 3054:1994 (CEN) is an aerospace series standard that defines the characteristics, dimensions and loads for single row self‑aligning roller bearings used in airframe rolling applications. These bearings are manufactured in steel with cadmium plating and are specifically designed to tolerate slow rotations, oscillations and swivelling under load. The standard covers use in components such as bell crank lever ends and the ends of rigid flight‑control rods, operating across an ambient range of −54 °C to +150 °C.

Key topics and requirements

• Scope and intended use: Bearings intended for airframe rolling where movement is limited to slow rotation, oscillation or swivel rather than continuous high‑speed rotation. Typical installation points include bell cranks and flight‑control rod ends (pre‑ or post‑servo).
• Material and plating: Steel construction with cadmium plating specified to meet corrosion and surface‑treatment needs of airframe applications.
• Dimensions: Geometrical data and dimensional series for single row self‑aligning roller bearings are specified (mounting envelopes, bore/outer diameters, widths) to ensure interchangeability.
• Load ratings: Static and applicable load characteristics are included to define safe working loads under the intended motion profiles.
• Temperature range: Rated for reliable performance from −54 °C to +150 °C, covering extreme environmental conditions encountered in aerospace service.
• Application constraints: Emphasis that these bearings are not for continuous high‑speed rotation but for slow, oscillatory or swivel motions under load.

Practical applications and users

Who uses EN 3054:1994:

• Aerospace design and structural engineers specifying bearings for control linkages, bell cranks and flight‑control rods.
• Bearing and component manufacturers producing cadmium‑plated, single row self‑aligning roller bearings to aerospace requirements.
• Procurement and quality assurance teams ensuring purchased bearings meet specified dimensions, load ratings and temperature performance.
• Maintenance, repair and overhaul (MRO) organizations selecting replacement bearings that match original airframe rolling specifications.
• Certification and compliance teams referencing standardized dimensions and loads for airworthiness documentation.

Related standards

• Other CEN/EN aerospace bearing series and national aerospace bearing specifications (for complementary bearing types and higher‑speed applications).
• General bearing standards (ISO) and aerospace industry documents (national aerospace standards like NAS) for broader bearing selection and material/treatment guidance.

EN 3054:1994 is a focused specification for airframe rolling applications where reliability under slow, oscillatory motion and wide temperature extremes is critical. Use it when defining, sourcing or validating single row self‑aligning roller bearings for flight‑control linkages and similar airframe components.
