Rolling bearings - Single-row cylindrical roller bearings - Chamfer dimensions for loose rib and non-rib sides

ISO 12043:2007 specifies the minimum chamfer dimensions for loose rib and non-rib sides of single-row cylindrical roller bearings of diameter series 0, 2, 3, and 4 (except dimension series 24) as specified in ISO 15. Indication is given for those minimum chamfer dimensions that are identical to those in ISO 15.

L'ISO 12043:2007 spécifie, pour les séries de diamètres 0, 2, 3 et 4 (à l'exception de la série 24), les dimensions minimales des arrondis des rondelles d'épaulement et des bagues côté sans épaulement des roulements à rouleaux cylindriques à une rangée, tels que spécifiés dans l'ISO 15. Des indications sont données pour les dimensions minimales des arrondis qui sont identiques à celles de l'ISO 15.

Overview

ISO 12043:2007 - "Rolling bearings - Single-row cylindrical roller bearings - Chamfer dimensions for loose rib and non-rib sides" specifies the minimum chamfer dimensions for the loose‑rib and non‑rib faces of single‑row cylindrical roller bearings. It applies to diameter series 0, 2, 3 and 4 (except dimension series 24) as defined in ISO 15. Minimum chamfer values are given in a tabular form (Table 1) in millimetres, and the Standard indicates where those minimums match the chamfer values already published in ISO 15. Maximum chamfer limits are referenced to ISO 582.

Key topics and requirements

  • Scope and applicability: Minimum chamfer dimensions for single‑row cylindrical roller bearings (diameter series 0, 2, 3, 4; excluding series 24).
  • Chamfer symbols and terms: Uses symbols defined in ISO 15241 and terminology from ISO 5593 (for example, r, r1s min).
  • Dimensional data: Table 1 provides the nominal minimum chamfer dimensions (r and r1s min) in millimetres for the covered diameter series and bore sizes.
  • Design coverage: Values are valid for both standard design and E‑design cylindrical roller bearings (E‑design indicates reinforced roller/cage assembly for increased radial load capacity).
  • Cross‑references: Points out when chamfer minima are identical to those in ISO 15 and refers to ISO 582 for maximum chamfer dimensions.
  • Normative references: ISO 15, ISO 582, ISO 5593, ISO 15241.

Practical applications

  • Ensures consistent bearing chamfer geometry to prevent interference with mating components (ribs, shoulders, housings) during assembly.
  • Reduces risk of edge stresses, improper seating, or roller/rib contact that could shorten bearing life.
  • Guides bearing designers and manufacturers when specifying internal edge radii for single‑row cylindrical roller bearings.
  • Helps quality control and inspection teams verify minimum chamfer compliance as part of incoming or final inspection criteria.
  • Useful for procurement and engineering teams specifying bearings for machinery where shaft shoulders or housing ribs interact with bearing faces.

Who uses this standard

  • Bearing designers and manufacturers
  • Mechanical engineers and machine designers
  • Quality assurance and inspection personnel
  • Purchasing/specification engineers
  • Standards bodies and certification organizations

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 2.
La tâche principale des comités techniques est d'élaborer les Normes internationales. 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 du présent document 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.
L'ISO 12043 a été élaborée par le comité technique ISO/TC 4, Roulements.
Cette deuxième édition annule et remplace la première édition (ISO 12043:1995), qui a fait l'objet d'une
révision technique.
