Overview

ISO 9448-4:2013 - Tools for pressing - Guide bushes - Part 4: Form C, gliding bushes, headed, type 1 specifies the standard geometry, tolerances and designation rules for headed gliding guide bushes (form C, type 1) used in press tools. It defines main dimensions (in millimetres), mounting method (in the clamp plate with a transition fit, fixed by screws), material guidance and required hardness. The document ensures interchangeability, correct assembly and consistent procurement of guide bushes for die sets.

Key topics and technical requirements

  • Dimensions and tolerances: Main guiding diameters, bush lengths and related dimensions are defined (see Figure 1 and Table 1 of the standard). Nominal guiding diameters covered include typical sizes such as 16, 20, 25, 32, 40 and 50 mm.
  • Mounting details: Designed to be mounted in the clamp plate with a transition fit and secured by screws. Clearance holes and screw sizes are addressed in the dimensional table.
  • Materials and hardness: Material selection is left to the manufacturer’s discretion, but hardness is specified as 60 HRC (Rockwell C) - test method per ISO 6508-1.
  • Design freedoms: Details not explicitly stated (chamfers, radii, lubrication grooves, surface roughness specifics) are left to the manufacturer’s discretion.
  • Designation rules: A guide bush is designated by:
    • “Guide bush”
    • reference to ISO 9448-4
    • form (C)
    • guiding diameter D (mm)
    • length l (mm) Example: Guide bush ISO 9448-4 C - 16 × 25
  • Anti-misassembly guidance: The standard recommends certain D1 values (for example 15, 19, 24, 30, 38 and 48 mm) to help prevent incorrect assembly of upper and lower plates.

Applications and who uses ISO 9448-4:2013

  • Press-tool designers and toolmakers specifying and designing die sets and guide systems.
  • Die manufacturers and stamping shops requiring standardized headed gliding bushes for repeatable alignments.
  • Procurement and quality engineers ensuring incoming parts meet dimensional and hardness requirements for interchangeability.
  • Maintenance teams and spare-part suppliers who need consistent designation and replacement sizing for headed gliding bushes.

Practical benefits include improved interchangeability, reduced assembly errors, clearer supplier specifications, and predictable wear performance due to specified hardness.

Related standards

  • Other parts of ISO 9448 (Parts 1–11): forms and types for plain, flanged, stepped and ball-cage bushes (e.g., ISO 9448-1, ISO 9448-2, ISO 9448-3, etc.).
  • ISO 6508-1: Metallic materials - Rockwell hardness test - Part 1: Test method (referenced for hardness verification).

Keywords: ISO 9448-4:2013, guide bushes, headed gliding bushes, press tools, dimensions and tolerances, 60 HRC, guide bush designation, clamp plate, transition fit.

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
