Full title and description

BS EN 2022:1990 — Specification for bearings, spherical plain in corrosion resisting steel with self-lubricating liner. Light series. Dimensions and loads. This European aerospace-series specification defines dimensional series, nominal loads and basic technical characteristics for light-series spherical plain bearings made from corrosion-resisting steel and fitted with a self‑lubricating liner intended primarily for aerospace and related applications.

Abstract

This standard gives the dimensional data, designation system, load ratings and related requirements for light-series spherical plain bearings in corrosion‑resisting steel with a self‑lubricating liner. It standardises tolerances, marking and designation so bearings from different manufacturers can be specified and interchanged for aircraft structure and control-mechanism applications.

Key bibliographic details and classification are taken from published listings of BS EN 2022:1990 and EN 2022 aerospace-series records.

Scope

Specifies dimensions, designation, nominal loads and basic technical requirements for light-series spherical plain bearings manufactured from corrosion‑resisting steel with a self‑lubricating liner. The scope covers bearings intended for fixed or moving parts of aircraft structures and control mechanisms and is intended to ensure interchangeability and minimum performance characteristics across manufacturers. It does not cover heavy-series designs, bearings in non‑aerospace industrial applications unless explicitly referenced, or detailed materials specifications beyond corrosion‑resisting steel and liner functional requirements.

Key topics and requirements

• Designation and marking conventions for light-series spherical plain bearings.
• Dimensional series and tolerances (inner/outer diameters, widths, spherical radii and related limits).
• Nominal static and dynamic load ratings / reference loads for each size in the light series.
• Materials: corrosion‑resisting (stainless) steel outer/inner members and requirements for self‑lubricating liner materials.
• Basic performance and inspection requirements (fit, running clearance, basic visual marking and identification).
• Reference to aerospace-series technical specifications and related normative documents for testing and verification.

Typical use and users

Primary users are aerospace component designers, aircraft systems engineers, bearing manufacturers and procurement specialists specifying bearings for aircraft structures and control linkages. Secondary users include maintenance organisations, quality assurance teams, and manufacturers of high‑performance machinery where aerospace‑grade spherical plain bearings with corrosion resistance and self‑lubricating liners are required. The standard supports selection, procurement and interchangeability of light‑series spherical plain bearings.

Related standards

EN 2022 is part of a wider aerospace-series family and references other aerospace technical specifications such as EN 2064 (technical specification for related bearing products) and other EN/Aerospace series documents covering materials and technical test methods. National and international equivalents / related documents (identical or closely aligned) include the original EN 2022 aerospace-series publications and the corresponding BS adoption record BS EN 2022:1990. Users should also review later or adjacent aerospace-series standards for heavy-series bearings, materials (e.g., specific stainless steels) and detailed testing requirements.

FAQ

Q: What is this standard?

A: BS EN 2022:1990 is the British-adopted version of the EN 2022 aerospace-series specification that defines dimensions, loads and designation for light-series spherical plain bearings made in corrosion‑resisting steel with a self‑lubricating liner.

Q: What does it cover?

A: It covers dimensional data, designation and marking, nominal loads and basic technical requirements needed to specify and interchange light‑series spherical plain bearings used primarily in aircraft structure and control mechanisms. It does not set out detailed metallurgical or manufacturing process controls beyond the functional requirement for corrosion‑resisting steel and a self‑lubricating liner.

Q: Who typically uses it?

A: Aerospace designers and engineers, bearing manufacturers and suppliers, procurement teams for aircraft components, and maintenance/quality personnel responsible for replacement and inspection of spherical plain bearings.

Q: Is it current or superseded?

A: The document as referenced (BS EN 2022:1990) is the British adoption of the EN aerospace-series text; users should verify whether a later EN revision or a newer aerospace specification has superseded it for their jurisdiction or application. National adoption records and CEN catalogues (and suppliers’ current product literature) should be checked for any amendments or superseding standards before specifying.

Q: Is it part of a series?

A: Yes — EN 2022 is part of the aerospace series of standards covering bearings and related components; related EN/Aerospace-series documents address different bearing types, sizes and technical specifications used across aircraft applications.

Q: What are the key keywords?

A: spherical plain bearing; light series; corrosion resisting steel; self‑lubricating liner; aerospace; dimensions; loads; BS EN 2022.
