Overview

EN 2022:1988 - published by CEN - defines the characteristics of spherical plain bearings manufactured from corrosion resisting steel and fitted with a self‑lubricating liner, designated as the light series. The standard covers the dimensions and load ratings for these bearings intended for aircraft use. Bearings covered are suitable for fixed and moving parts of the aircraft structure and control mechanisms and are specified for operation in the temperature range ‑55 °C to +150 °C.

Key topics and requirements

• Scope and application: Bearings for aerospace structural and control mechanism use (light series).
• Materials: Requirement for corrosion‑resisting steel housings and mating components (standard identifies material class; consult material standards for composition and treatment).
• Self‑lubricating liner: Specification of bearings intended to operate with an integral self‑lubricating liner to reduce maintenance and provide reliable motion in flight conditions.
• Dimensions: Defined geometric sizes and tolerances for the light series to ensure interchangeability and proper fit in aircraft assemblies.
• Load ratings: Designated static and dynamic loading characteristics appropriate to the light series; the standard specifies allowable loads for the intended applications.
• Environmental range: Rated for continuous use between ‑55 °C and +150 °C, addressing extreme atmospheric and operational conditions typical in aerospace service.
• Intended use: Suitable for fixed and moving joints within aircraft structures and control mechanisms where corrosion resistance and low maintenance are required.
• Compliance and documentation: National adoptions (e.g., SIST EN 2022:2001) and reproduction restrictions are noted for official copies.

Applications

• Aircraft structural joints where low friction and corrosion resistance are required.
• Control linkages and actuation pivots subject to cyclic motion and limited lubrication access.
• Components in landing and flight control systems where light‑series bearings provide weight and space advantages.
• Aerospace suppliers specifying interchangeable bearings for design, procurement, and maintenance.

Who uses this standard

• Aerospace design and structural engineers specifying bearing types.
• Procurement and sourcing teams ensuring part compliance.
• Bearing manufacturers and suppliers producing aviation‑grade spherical plain bearings.
• Maintenance, repair and overhaul (MRO) organizations selecting replacement parts.
• Certification and quality assurance teams verifying conformance to aerospace standards.

Related standards

• Other CEN/ISO aerospace bearing standards covering different bearing types, materials, or heavier series.
• Material and corrosion‑resistance standards for stainless and corrosion‑resisting steels.
• Lubrication and testing standards for aerospace components.
