Rolling bearings — Chamfer dimensions — Geometrical product specification (GPS) and values

Cancels and replaces the second edition (1979). Specifies the maximum chamfer dimensions of metric series rolling bearings, for which boundary dimensions, including chamfer minimum dimensions, are given in other International Standards. Gives also requirements for the maximum dimensions of the corresponding shaft and housing filet radii. Does not apply to chamfers, for which dimensions are not specified, or for which other dimensions are specified in other International Standards.

Roulements — Dimensions des arrondis — Spécification géométrique des produits (GPS)

La présente Norme internationale prescrit les dimensions maximales des arrondis des roulements de la série métrique, dont les dimensions d'encombrement, y compris les dimensions minimales d'arrondi, sont données dans d'autres Normes internationales ISO. Elle définit également le rayon maximal correspondant des congés d'arbre et de logement. La présente Norme internationale ne s'applique pas aux arrondis des roulements dont les dimensions ne sont pas normalisées, ou pour lesquels d'autres dimensions sont données dans les Normes internationales ISO correspondantes.

Overview

ISO 582 - Rolling bearings - Chamfer dimensions - Geometrical product specification (GPS) and values (FDIS 582:2025) defines how chamfers on metric-series rolling bearings are specified and controlled to ensure interchangeability and reliable assembly. The fourth edition (2025) replaces ISO 582:1995, aligns chamfer representation with ISO GPS rules (ISO 8015) and ISO 21204 transition specifications, and updates symbols and annex material. The standard provides nominal chamfer boundaries and corresponding recommendations for maximum shaft and housing fillet radii.

Key topics and technical requirements

  • Scope and purpose: Specifies chamfer least‑material boundaries for rings and washers and the radius maximum‑material boundaries that contain those chamfers. Aims to minimize assembly incompatibility and to ensure adequate ring support surfaces.
  • GPS-based representation: Uses Geometrical Product Specification (GPS) transition specifications (ISO 8015, ISO 21204) to show limiting material boundaries - the chamfer least material boundary (CL) and the radius maximum material boundary (RM).
  • Symbols and notation: Standardizes symbols (for example c, cr, c1r, r, r1) in accordance with ISO 22872 and relates them to earlier editions (see Annex A).
  • Dimensional data tables: Provides tabulated nominal chamfer dimensions for common bearing families (radial bearings, tapered roller bearings, thrust bearings, washers) in Tables 3–7. These tables give the nominal axial and radial extents and the RM radii for specified bore/outside diameter ranges.
  • Shaft and housing fillet radii: States that recommended fillet radii of mating shafts and housings should not exceed the nominal radius of the bearing’s RM; guidance and figures illustrate acceptable relations.
  • Applicability limits: Does not apply where chamfer dimensions are unspecified or are controlled by other international standards.

Applications and users

ISO 582 is practical for:

  • Bearing designers and manufacturers specifying ring and washer chamfers for metric series bearings.
  • Mechanical engineers and machine designers ensuring bearing interchangeability and safe assembly.
  • Drafting, quality control and inspection teams who interpret GPS transition specifications on drawings.
  • Procurement and standards teams verifying component compliance across suppliers.

Practical benefits include easier mounting, reduced risk of interference with mating fillets, consistent drawing notation, and improved cross‑supplier compatibility.

Related standards

  • ISO 5593 (rolling bearings vocabulary)
  • ISO 8015 (GPS fundamentals)
  • ISO 21204 (GPS transition specification)
  • ISO 22872 (GPS - bearing vocabulary and symbols)
  • Bearing family standards that reference ISO 582 tables: ISO 15, ISO 104, ISO 246, ISO 355, ISO 464, ISO 12043, ISO 12044

Keywords: ISO 582, rolling bearings, chamfer dimensions, GPS, geometrical product specification, bearing chamfer, shaft fillet radius, housing fillet radius, interchangeability, bearing design.

Avant-propos
L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes nationaux
de normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est en général
confiée aux comités techniques de l'ISO. Chaque comité membre intéressé par une étude a le droit de faire
partie du comité technique créé à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec l'ISO participent également aux travaux. L'ISO collabore étroitement avec
la Commission électrotechnique internationale (IEC) en ce qui concerne la normalisation électrotechnique.
Les procédures utilisées pour élaborer le présent document et celles destinées à sa mise à jour sont
décrites dans les Directives ISO/IEC, Partie 1. Il convient, en particulier, de prendre note des différents
critères d'approbation requis pour les différents types de documents ISO. Le présent document a
été rédigé conformément aux règles de rédaction données dans les Directives ISO/IEC, Partie 2 (voir
www.iso.org/directives).

révision technique. Elle incorpore également l'Amendement ISO 582:1995/Amd. 1:2013.
Les principales modifications sont les suivantes:
— implémentation de l'ISO 21204;
— révision des symboles;
— ajout des Annexes A et B.

Introduction
Le but du présent document est d'obtenir l'interchangeabilité des roulements, en spécifiant les dimensions
d'arrondi, et de minimiser le risque d'incompatibilité dans les applications de roulements, ainsi que de
faciliter le processus de montage.
La spécification des dimensions d'arrondi garantit également une surface support suffisante pour les bagues
de roulement.

géométrique des produits (GPS)
1 Domaine d'application
Le présent document spécifie la limite de l'arrondi au minimum de matière pour les arrondis de bague
et de rondelle de roulements de séries métriques pour les limites de rayon au maximum de matière
correspondantes. Les limites de rayon au maximum de matière sont données dans les Références [1], [2], [3],
[4], [5], [6], [7].
Des recommandations sont données pour les rayons maximaux des congés de logement et d’arbre
correspondants.
