Full title and description

BS ISO 9448-5:2013 / ISO 9448-5:2013 — Tools for pressing — Guide bushes — Part 5: Form D, ball cage bushes, headed, type 1. This document specifies the principal dimensions, tolerances, guidance on materials and hardness, and the designation of form D headed ball‑cage guide bushes intended for use in press tools; it is published by ISO and has been adopted as a British Standard (BS ISO 9448-5:2013).

Abstract

ISO 9448-5:2013 specifies main dimensions and tolerances (in millimetres) for guide bushes of form D (headed, ball‑cage bushes, type 1) intended to be mounted in the clamp plate with a transition fit and fixed by screws. The part also gives guidance on suitable materials and specifies required hardness and designation conventions for these bushes.

Scope

This part of ISO 9448 specifies the main dimensions, tolerances and designation rules for form D headed ball‑cage guide bushes (type 1) to be used in press tools. It covers mounting (transition fit and screw fixing), gives guidance on materials and specifies required hardness and marking/identification conventions for these bushes. It is intended to standardize interchangeability and quality of guide bushes used in tooling for pressing operations.

Key topics and requirements

• Standardized main dimensions and dimensional tolerances (millimetres) for form D headed ball‑cage bushes.
• Designation and marking rules for identification of bush types and sizes.
• Guidance on suitable materials and required hardness ranges for durable service in press tools.
• Mounting and fit recommendations — transition fit into clamp plate and fixing by screws.
• Compatibility/interchangeability considerations for toolmakers and spare‑part suppliers.

Typical use and users

Used by press‑tool designers, toolmakers, maintenance engineers, procurement and quality managers in metal‑forming and stamping industries, and by standards/technical libraries for specification and verification of guide bushes. The part supports consistent manufacture, selection and replacement of headed ball‑cage guide bushes in production tooling.

Related standards

ISO 9448 is a multipart series covering guide bushes for pressing tools; related parts include other forms and types in the ISO 9448 series (for example Parts 1, 2, 3, 4, 6, 7, 8, 9, 11, etc.). Users often consult other ISO 9448 parts for different bush forms and mounting methods when designing or specifying tooling.

FAQ

Q: What is this standard?

A: ISO 9448-5:2013 (published as BS ISO 9448-5:2013 when adopted nationally) is the part of the ISO 9448 series that defines main dimensions, tolerances, material guidance and designation for form D headed ball‑cage guide bushes used in press tools.

Q: What does it cover?

A: It covers the geometric dimensions and tolerances (in millimetres), mounting fit (transition fit into clamp plates), fixing by screws, material and hardness guidance, and the designation/identification system for form D, ball‑cage, headed, type 1 guide bushes.

Q: Who typically uses it?

A: Tool designers, toolmakers, production and maintenance engineers in metal‑forming/stamping operations, procurement and quality assurance teams, and standards librarians use this part to ensure interchangeability and correct specification of guide bushes.

Q: Is it current or superseded?

A: ISO 9448-5:2013 is published and was last reviewed/confirmed by ISO in 2019, and the ISO record indicates the edition remains current while subject to normal periodic review. Nationally adopted versions (for example BS ISO 9448-5:2013) were published subsequently (BS listing shows publication 31 January 2014). Users should check with their national standards body for any more recent national amendments or replacements.

Q: Is it part of a series?

A: Yes — it is Part 5 of the ISO 9448 series (Tools for pressing — Guide bushes). The series contains multiple parts that define different forms and types of guide bushes and mounting methods; consult the ISO 9448 series index for other parts relevant to your application.

Q: What are the key keywords?

A: Guide bushes, guide bushings, Form D, headed, ball‑cage, press tools, dimensions, tolerances, hardness, materials, designation.
