Overview
ISO 9448-10:2013 is an international standard published by ISO that specifies the main dimensions, tolerances, materials, and designations for guide bushes of form E - flanged gliding bushes, type 2. These guide bushes are critical components used in press tools with guide pillars and are designed to ensure precision and durability in tooling applications. The standard addresses guide bushes intended to be mounted in a clamp plate by means of guide clamps and with a transition fit, conforming to the tolerance class g6 for the guiding diameter according to ISO 9182-3.
This standard provides manufacturers and users with detailed technical specifications in millimetres, promoting consistency and interchangeability in press tool components. ISO 9448-10:2013 forms part of the broader ISO 9448 series which covers different forms and types of guide bushes for pressing tools.
Key Topics
-
Dimensions and Tolerances
The standard defines exact measurements for type 2 flanged gliding bushes, including diameter, length, flange thickness, and tolerances. For example:
- Guiding diameter tolerance of g6 for the guide pillar interface
- Clamp plate hole tolerance of H7
- Chamfers, radii, and lubrication grooves are customizable at the manufacturer’s discretion
-
Material Requirements
Material selections are agreed upon between manufacturers and end-users to meet performance needs, including hardness specification referencing Rockwell hardness tests according to ISO 6508-1.
-
Designation and Identification
Guide bushes are designated clearly to reflect compliance with this standard. Designation format includes:
- The term “Guide bush”
- The standard reference ISO 9448-10
- The form identifier E
- The guiding diameter in millimetres (e.g., Guide bush ISO 9448-10 E - 25)
-
Installation and Usage
The bushes are intended for mounting with a transition fit in clamp plates and fixed using guide clamps, ensuring precise alignment with guide pillars as per ISO 9182-3.
Applications
ISO 9448-10:2013 guide bushes are essential in various press tooling applications including:
- Metal forming and stamping operations where precision guide bushes help maintain alignment and reduce wear between guide pillars and press tools
- Manufacturing environments that require standardized replaceable bushes to ensure consistent performance and maintenance ease
- Automotive, aerospace, and industrial fabrication sectors that rely on high-precision press tools featuring standardized gliding bushes for optimal durability and functionality
- Tool maintenance and tool design processes that depend on clear specifications for easy selection, replacement, and quality control of guide bushes
By standardizing the form, dimensions, and fitting methods, ISO 9448-10:2013 reduces tooling costs and downtime, improving productivity in press tool manufacturing and maintenance.
