The following types of terms are not included: — terms specified in ISO 76, ISO 281 and ISO 1132-1; — terms which are narrowly applied in only one specialized rolling bearing International Standard.

Roulements — Vocabulaire

Le présent document définit les termes appliqués dans le domaine des roulements et de leur technologie. Le présent document contient des termes associés à tous les types de roulements dans lesquels le principal degré de liberté est une rotation continue autour d'un axe, rendue possible par un ensemble ordonné d'éléments roulants entre deux chemins de roulement circulaires, de telle sorte que les charges puissent être transmises entre eux dans une plage particulière de directions radiales, axiales, ou les deux. Le présent document inclut également les accessoires associés à ces produits. Les types de termes suivants ne sont pas inclus: — les termes spécifiés dans les ISO 76, ISO 281 et ISO 1132‑1; — les termes qui ne sont utilisés que dans une Norme internationale spécialisée relative aux roulements.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

1 S cope
This document defines terms applied in the field of rolling bearings and their technology.
This document includes terms related to all types of rolling bearings wherein the principal degree of

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

Rolling bearings — Vocabulary
1 S cope
This document defines terms applied in the field of rolling bearings and their technology.
This document includes terms related to all types of rolling bearings wherein the principal degree of

radial or axial directions, or both. This document also includes accessories to these products.
The following types of terms are not included:
— terms specified in ISO 76, ISO 281 and ISO 1132-1;
— terms which are narrowly applied in only one specialized rolling bearing International Standard.
