Overview
ISO 9448-7:2013 specifies the main dimensions, tolerances and basic technical requirements for form F, flanged ball cage guide bushes, type 1, used in press tools. The standard covers mounting details (intended for installation in the clamp plate with a transition fit and fixation by guide clamps), material guidance, required hardness and the standardized method of designation. Dimensions are given in millimetres and referenced in the standard’s Figure 1 and Table 1.
Keywords: ISO 9448-7:2013, guide bushes, ball cage bushes, flanged, press tools, form F, type 1
Key topics and technical requirements
- Scope and form: Applies to flanged ball cage bushes (Form F), Type 1, for use in press tooling.
- Dimensions and tolerances: Main dimensions and tolerances are specified in the standard’s figures and tables (manufacturer to follow Table 1 and Figure 1 for nominal sizes).
- Mounting fit: Designed to be mounted in the clamp plate with a transition fit and fixed by guide clamps; intended to fit into a hole of tolerance H7.
- Internal diameter (D1): Manufacturer determines the internal diameter using tolerance M5. This diameter is intended to be lapped or ground for correct ball preloading.
- Surface finish: Lapped or ground internal diameter to a surface roughness Ra = 0.05 µm; this diameter acts as the reference for concentricity and perpendicularity tolerances.
- Material and hardness: Material choice is at the manufacturer’s discretion; required hardness is (63 ± 1) HRC (see ISO 6508-1 for Rockwell test method).
- Manufacturer discretion: Unspecified features (chamfers, radii, lubrication grooves, number of guide clamps) are left to the manufacturer.
- Designation format: Standardized designation example - Guide bush ISO 9448-7 F - 12 × 20 × 30 (form, guiding diameter D, lengths l1 and l2).
Applications and users
- Primary use: Precision guide bushes for press tools and die sets where ball-guided movement is required.
- Who uses it:
- Tool and die designers and manufacturers
- Press/tooling maintenance teams and workshop engineers
- Component suppliers and mechanical engineers specifying guide bushes for stamping, forming or molding operations
- Practical value:
- Ensures interchangeability of guide bushes across suppliers
- Provides repeatable preloading and low-friction guidance via ball cages
- Reduces risk of incorrect plate assembly by following recommended diameter choices and designation rules
Related standards
- ISO 9448 (other parts cover different forms and types of guide bushes - Parts 1–11)
- ISO 6508-1 - Metallic materials: Rockwell hardness test (referenced for hardness measurement)
This standard is essential when specifying flanged ball cage guide bushes for press tooling to ensure dimensional compatibility, correct fit (H7/M5), surface finish (Ra 0.05 µm) and the required hardness (63 ± 1 HRC).

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. www.iso.org/directives

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 9448-7 a été élaborée par le comité technique ISO/TC 29, Petit outillage, sous-comité SC 8, Outillage
de presse et de moulage.
Cette deuxième édition résulte de la réintégration de l’ISO 9448-7:1991, qui a été annulée en 2006 et
dont le contenu technique était identique.
L’ISO 9448 comprend les parties suivantes, présentées sous le titre général Outillage de presse — Bagues
