Full title and description

ISO 1002:1983 — Rolling bearings — Airframe bearings — Characteristics, boundary dimensions, tolerances, static load ratings. Specifies characteristics, boundary dimensions, tolerances and basic static load ratings for rolling bearings (other than tapered roller bearings) used in airframe structures; covers both metric and inch series and typically applies to full‑complement, sealed or shielded bearings used in aircraft structural applications.

Abstract

Applies to rolling bearings used in airframe structures (excluding tapered roller bearings). Defines the term “airframe”, includes both metric and inch series bearings and specifies essential characteristics, seals/shields, protection against corrosion, boundary dimensions, tolerances and basic static radial load ratings, together with dimension and tolerance tables and an annex on permissible loads.

Scope

Specifies requirements for rolling bearings used in airframe structures except tapered roller bearings. Includes both metric and inch series in recognition of aircraft industry practice, and focuses on bearings that are normally full‑complement with cylindrical bores and outer surfaces, usually sealed or shielded. The standard provides dimension tables, tolerance and radial clearance tables for both metric and inch series and basic static radial load ratings.

Key topics and requirements

• Definition and classification of airframe bearings (excludes tapered roller bearings).
• Essential characteristics required for airframe applications (seals/shields, corrosion protection).
• Boundary (envelope) dimensions for metric and inch series bearings.
• Tolerances and recommended radial clearances (tables for metric and inch series).
• Basic static radial load ratings and an annex on permissible loads.
• Dimension and tolerance tables to support design, procurement and inspection.

Typical use and users

Used by aerospace engineers, structural component designers, bearing manufacturers and suppliers, quality and inspection engineers, maintenance organizations and procurement specialists specifying airframe bearings or verifying interchangeability and static load requirements in aircraft structural applications.

Related standards

ISO 1002:1983 cancels and replaced ISO Recommendation R 1002‑1969 (technical revision). A later national/adopted editions exist (for example DIN adopted as DIN ISO 1002). A subsequent related edition/revision is listed as ISO 1002:2001 (SIST ISO 1002:2001 references). Other bearing series and tolerance standards (ISO 15 and various ISO rolling‑bearing standards) are commonly used alongside ISO 1002 in practice.

FAQ

Q: What is this standard?

A: ISO 1002:1983 is an ISO International Standard that specifies characteristics, envelope dimensions, tolerances and basic static load ratings for rolling bearings used in airframe (aircraft structural) applications.

Q: What does it cover?

A: It covers non‑tapered rolling bearings used in airframe structures — both metric and inch series — and includes tables of dimensions, tolerances, radial clearances, basic static radial load ratings, plus requirements for seals/shields and corrosion protection.

Q: Who typically uses it?

A: Aerospace designers and engineers, bearing manufacturers and suppliers, inspectors, maintenance organizations and procurement specialists specifying or verifying airframe bearings.

Q: Is it current or superseded?

A: ISO 1002:1983 is the first edition published in 1983 and is recorded as published/confirmed in ISO’s lifecycle records; there is a later related edition/reference (ISO 1002:2001 in national/translated publishing) and national adoptions (for example DIN ISO 1002). Users should check the ISO catalogue or national standards body for the most current version or any later revisions before specifying.

Q: Is it part of a series?

A: It sits within the family of rolling‑bearing and aerospace component standards (ICS 49.035 and ISO/TC 20 work). It is related to other ISO rolling‑bearing standards (for general bearing dimensions, tolerances and specific bearing types) and to national adoptions/adaptations.

Q: What are the key keywords?

A: Airframe bearings; rolling bearings; boundary dimensions; tolerances; static load ratings; metric/inch series; seals; corrosion protection.
