Full title and description

Rolling bearings — Bearings with spherical outside surface and extended inner ring width. This international standard specifies the defining characteristics and dimensional conventions for rolling bearings that have a spherical outer surface combined with an inner ring of extended width, including designation and basic application notes for such bearing types.

Abstract

ISO 2264:1972 establishes the principal dimensions, tolerances and characteristic features for a family of rolling bearings whose outer surface is spherical and whose inner ring has an extended width. The document covers dimensional series, marking/identification and certain mounting/locking features relevant to these bearings. The edition was published in 1972 and has since been withdrawn and superseded by later work in the rolling‑bearings series.

Scope

This standard applies to rolling bearings with a spherical outside surface and an inner ring of extended width. It defines the dimensional characteristics, basic geometric series and designation rules needed to ensure interchangeability and consistent specification of such bearings. It does not replace broader product or performance standards for load ratings, lubrication or specific material specifications.

Key topics and requirements

• Dimensional series and nominal sizes for bearings with spherical outside surfaces.
• Specified widths for extended inner rings and related geometric tolerances.
• Designation and marking conventions to identify bearing type and key dimensions.
• Guidance on locking/mounting features associated with the extended inner ring.
• Notes on interchangeability and limits of application (scope exclusions for performance data).

These topics reflect the technical content and headings found in the original 1972 text.

Typical use and users

Primary users include bearing designers and manufacturers, mechanical design engineers specifying bearings for housings with spherical outer seats, maintenance and procurement specialists who reference dimensional standards for replacement parts, and national standards bodies for historical reference or when mapping legacy part numbers to modern standards.

Related standards

ISO 2264:1972 has been withdrawn and the subject matter was later addressed by subsequent ISO work in the rolling‑bearings family. It is reported as revised by ISO 9628:1992 (and related ISO/TC 4 publications on bearing inserts and locking collars). Users mapping legacy documents should consult the later ISO rolling‑bearing standards and current ISO/TC 4 deliverables for up‑to‑date requirements.

FAQ

Q: What is this standard?

A: ISO 2264:1972 is an international standard that defined dimensions and basic characteristics for rolling bearings with a spherical outer surface and an extended‑width inner ring.

Q: What does it cover?

A: It covers nominal dimensions, width conventions for the extended inner ring, designation/marking rules and related geometric tolerances needed for specifying and identifying these bearing types. It does not provide performance ratings (load, life) or detailed material specifications.

Q: Who typically uses it?

A: Bearing manufacturers, mechanical designers, procurement and maintenance engineers, and standards/technical librarians who handle legacy bearing specifications.

Q: Is it current or superseded?

A: ISO 2264:1972 has been withdrawn. The subject was addressed by later ISO work (notably ISO 9628:1992 and other rolling‑bearings publications). Users should consult the current ISO rolling‑bearing standards for up‑to‑date requirements.

Q: Is it part of a series?

A: Yes — it was produced under ISO/TC 4 (Rolling bearings) and belongs to the broader family of ISO rolling‑bearing standards that cover dimensions, tolerances, designation and special bearing types.

Q: What are the key keywords?

A: Rolling bearings; spherical outside surface; extended inner ring; dimensions; tolerances; designation; ISO 2264; withdrawn.
