ISO 9448-2:2013 specifies the main dimensions and tolerances, in millimetres, of guide bushes of form A, plain gliding bushes, type 1, intended for use in press tools and to be mounted in the clamp plate by means of interference fit. It gives guidance on the materials, and specifies the hardness and the designation of bushes in accordance with ISO 9448-2:2013.

Outillage de presse — Bagues de guidage — Partie 2: Forme A, bagues lisses pour guidage lisse, type 1

L'ISO 9448-2:2013 prescrit les principales dimensions et tolérances, en millimètres, des bagues de guidage de forme A, bagues lisses pour guidage lisse, type 1, destinées à être utilisées dans les outillages de presse et devant être montées dans une semelle par ajustement serré. Elle donne des indications relatives aux matériaux, prescrit une dureté et spécifie la désignation des bagues conformes à l'ISO 9448-2:2013.

Overview

ISO 9448-2:2013 specifies the main dimensions and tolerances (in millimetres) for guide bushes of Form A - plain, gliding bushes (type 1) - intended for use in press tools. The standard defines how these bushes are to be mounted (interference fit in the clamp plate), gives guidance on materials, prescribes the required hardness, and sets out the designation format for compliant parts.

Key Topics and Requirements

• Scope: Applies to Form A, plain gliding guide bushes, type 1, for press tooling.
• Dimensions & tolerances: Main sizes, lengths and dimensional tolerances are given (see Figure 1 and Table 1 in the standard). Surface roughness values are indicated in micrometres in the figure.
• Mounting fit: Designed to be mounted in the clamp plate by interference fit (hole tolerance H7 recommended). When bushes are glued, tolerance j6 may be permitted.
• Material & hardness: Material choice is left to the manufacturer; however, the hardness is specified at 60 HRC.
• Standard designation: Format for marking/ordering:
  Example - “Bague de guidage ISO 9448-2 A – 12 × 25” (Guide bush ISO 9448-2 A – D × l), where D is guide diameter and l is length in mm.
• Recommended diameters: To help prevent incorrect assembly of upper and lower die shoes, recommended D values include 11, 15, 19, 24, 30, 38 and 48 mm.
• Documentation: Bibliography references include ISO 6508-1 (Rockwell hardness test method) for hardness verification.

Applications and Users

This standard is practical for professionals and organizations involved in:

• Press-tool and die design - selecting and specifying standardized guide bushes.
• Tool and die manufacturers - producing or sourcing compliant guide bush dimensions and surface finish.
• Maintenance and repair of presses - replacing worn bushes with correctly sized, hardened parts.
• Quality assurance and procurement - verifying tolerances, fit (H7 / j6), and hardness (60 HRC).
• OEMs and component suppliers - ensuring interchangeability and consistent performance in stamping and forming operations.

Benefits include improved interchangeability, reduced risk of mismatched parts in die assemblies, and predictable wear behavior due to specified hardness.

Related Standards

• ISO 9448 (series) - other parts cover different forms and types (Parts 1, 3–11 address alternative shapes, collars, ball-guided variants and type 2 versions).
• ISO 6508-1 - Rockwell hardness test method referenced for hardness compliance.

Keywords: ISO 9448-2:2013, guide bushes, guide bush dimensions and tolerances, press tools, gliding bushes, hardness 60 HRC, H7 interference fit, guide bush designation.

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

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.
