Overview

ISO 9448-11:2013 is an international standard published by ISO that defines the specifications for tools for pressing, specifically focusing on guide bushes of form F, which are flanged ball cage bushes, type 2. These components are crucial in the manufacture and operation of press tools, where precision guiding is necessary for reliable and consistent performance.

This standard outlines the main dimensions and tolerances (expressed in millimetres) required for these guide bushes, and provides guidance on appropriate materials, hardness levels, and product designation. The guide bushes covered by ISO 9448-11:2013 are designed to be mounted in the clamp plate of press tools using a transition fit and secured by guide clamps.

Key Topics

• Dimensions and Tolerances: The standard specifies detailed dimensions for type 2 flanged ball cage bushes, including diameters, lengths, and flange thickness, ensuring compatibility and interchangeability. Surface roughness and precision tolerances for internal diameters are highlighted, facilitating the right fit and function.

• Material and Hardness: While the choice of material is left to the manufacturer’s discretion, the hardness requirement is clearly stated as (63 ± 1) HRC, ensuring durability and resistance to wear in demanding press tool environments.

• Designation System: A standardized method for designating guide bushes is defined, enabling clear identification and communication. Each bush is labeled by its form, guiding diameter, and length, e.g., Guide bush ISO 9448-11 F - 25 × 25.

• Mounting and Usage: The guide bushes are intended for installation in the clamp plate of press tools with a transition fit and fixed by guide clamps. This ensures stable positioning and proper preloading of the ball cage mechanism.

Applications

ISO 9448-11:2013 guide bushes are predominantly used in:

• Press tools and moulding equipment: Ensuring precise linear guidance of moving components during pressing and forming operations.
• Manufacturing and metalworking industries: Where repeatable, accurate movement is necessary to maintain quality and efficiency in tool operation.
• Automation and tooling systems: Providing standardized parts that streamline design, maintenance, and replacement processes.
• Heavy-duty industrial presses: Enhancing the lifespan and performance of tooling by offering high hardness and well-defined tolerances on wear components.

Using standardized guide bushes reduces downtime, improves alignment accuracy, and extends tool life in various industrial settings.

Related Standards

• ISO 9448 series: This standard is part 11 of the ISO 9448 series covering various forms and types of guide bushes for pressing tools, including:

  • Part 1: General Forms
  • Part 7: Form F, ball cage bushes, flanged, type 1
  • Part 9: Form B, ball cage bushes, plain, type 2
  • Other parts addressing different forms (A, B, C, D, E, G) and types (1 and 2)

• ISO 6508-1: Metallic materials – Rockwell hardness test – Part 1: Test method, referenced for hardness testing applied in guide bush material specifications.

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

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.
