Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 3290 was prepared by Technical Committee ISO/TC 4, Rolling bearings.
This third edition cancels and replaces the second edition (ISO 3290:1998) which has been technically revised.
Annexes A and B form a normative part of this International Standard.

INTERNATIONAL STANDARD ISO 3290:2001(E)

Rolling bearings — Balls — Dimensions and tolerances
1 Scope
This International Standard specifies requirements for finished steel balls for rolling bearings.
2 Normative references
The following normative documents contain provisions which, through reference in this text, constitute provisions of
this International Standard. For dated references, subsequent amendments to, or revisions of, any of these
publications do not apply. However, parties to agreements based on this International Standard are encouraged to
investigate the possibility of applying the most recent editions of the normative documents indicated below. For
undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC
maintain registers of currently valid International Standards.

3 Terms and definitions
For the purposes of this International Standard, the terms and the definitions given in ISO 1132-1, ISO 5593 and
ISO 15241 and the following apply.
3.1
nominal ball diameter
D

single ball diameter
D
ws
distance between two parallel planes tangential to the actual surface of a ball

3.4
variation of ball diameter
V
Dws
difference between the largest and the smallest of the single diameters of a ball
3.5
surface irregularities and form parameters
various types of deviation from the perfect spherical ball surface, uniformly distributed and repeated around the ball
surface
NOTE The deviations to which limits can be attributed are:
 deviation from spherical form;
 waviness;
 surface roughness.
3.5.1
deviation from spherical form
greatest radial distance, in any equatorial plane, between the smallest circumscribed sphere and the greatest
inscribed sphere, with their centres common to the least square sphere centre
NOTE Information about the measurement of this deviation is given in annex A.

NOTE It is recommended that waviness be evaluated as velocity amplitude. In practice, the waviness components are
separated from the real surface by a waviness analyser (filters).
3.5.3
surface roughness
surface irregularities with relatively small spacings, which usually include irregularities resulting from the method of
manufacture being used and/or other influences
NOTE These irregularities are considered within the limits that are conventionally defined, e.g., within the limits of the
sampling length.
3.6
surface defect
element, irregularity or group of elements and irregularities of the real surface, unintentionally or accidentally
caused during manufacture, storage, handling or use of the surface
NOTE These types of element or irregularity differ considerably from those constituting the surface roughness and should
not be considered during the measurement of the surface roughness (see 4.2, note 2). Surface defects (and their limits) are not
specified in this International Standard.

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 (CEI) en ce qui concerne la normalisation électrotechnique.
Les Normes internationales sont rédigées conformément aux règles données dans les Directives ISO/CEI, Partie 3.
Les projets de Normes internationales adoptés par les comités techniques sont soumis aux comités membres pour
vote. Leur publication comme Normes internationales requiert l'approbation de 75 % au moins des comités
membres votants.
L’attention est appelée sur le fait que certains des éléments de la présente Norme internationale peuvent faire
l’objet de droits de propriété intellectuelle ou de droits analogues. L’ISO ne saurait être tenue pour responsable de
ne pas avoir identifié de tels droits de propriété et averti de leur existence.
La Norme internationale ISO 3290 a été élaborée par le comité technique ISO/TC 4, Roulements.
Cette troisième édition annule et remplace la deuxième édition (ISO 3290:1998), dont elle constitue une révision
technique. En particulier, dans le Tableau 1, les diamètres nominaux de billes, en millimètres, qui étaient exprimés
avec trois décimales le sont maintenant avec cinq décimales.
Les annexes A et B constituent des éléments normatifs de la présente Norme internationale.

constituent des dispositions valables pour la présente Norme internationale. Pour les références datées, les
amendements ultérieurs ou les révisions de ces publications ne s’appliquent pas. Toutefois, les parties prenantes
aux accords fondés sur la présente Norme internationale sont invitées à rechercher la possibilité d'appliquer les
éditions les plus récentes des documents normatifs indiqués ci-après. Pour les références non datées, la dernière
édition du document normatif en référence s’applique. Les membres de l'ISO et de la CEI possèdent le registre des
Normes internationales en vigueur.

différence entre le plus grand et le plus petit des diamètres isolés d’une bille
3.5
irrégularités de surface et paramètres de forme
différents types d’écarts par rapport à la surface parfaite d’une bille sphérique, distribués et répétés uniformément
autour de la surface de la bille
NOTE Les écarts auxquels des limites peuvent être allouées sont:
 écarts de sphéricité;
 ondulation;
 rugosité de surface.
3.5.1
écart de sphéricité
plus grande distance radiale, en tout plan équatorial, entre la plus petite sphère circonscrite et la plus grande
sphère inscrite ayant leur centre commun au centre de la sphère des moindres carrés
NOTE Des indications concernant la mesure de cet écart sont données dans l’annexe A.
3.5.2
ondulation
irrégularités de surface présentant un écart aléatoire ou périodique par rapport à la sphère idéale
NOTE Il est recommandé d’évaluer l’ondulation comme une amplitude de vitesse. En pratique, les composantes de
l’ondulation sont discriminées à partir de la surface réelle par un analyseur d’ondulation (filtres).
3.5.3
rugosité de surface
irrégularités de surface, relativement faiblement espacées, qui englobent habituellement les irrégularités résultant
du processus de fabrication mis en œuvre et/ou d’autres facteurs d’influence
NOTE Ces irrégularités sont considérées dans des limites définies conventionnellement, par exemple, dans les limites de la
longueur de base.
3.6
défaut de surface
élément, irrégularité ou groupe d’éléments et d’irrégularités de la surface réelle, provoqués non intentionnellement
ou accidentellement pendant la fabrication, le stockage, la manutention ou l’utilisation de la surface
NOTE Ces types d’éléments ou d’irrégularités diffèrent considérablement de ceux constitutifs de la rugosité de surface, et
il convient de ne pas les prendre en compte au cours du mesurage de la rugosité de surface (voir 4.2, note 2). Les défauts de
surface (et leurs limites) ne sont pas spécifiées dans la présente Norme internationale.
