ISO 9182-3:2023

Overview

ISO 9182-3:2023 - Tools for pressing - Guide pillars - Part 3: Type B, end-locking pillars - specifies the dimensions, tolerances, material guidance, hardness and designation rules for Type B guide pillars used in press tools. This fourth edition updates Type B1/B2 configurations and the required hardness. The standard is essential for consistent design, manufacture and procurement of guide pillars in stamping, moulding and press tooling operations.

Key topics and technical requirements

• Scope: Dimensional and tolerance requirements for Type B guide pillars (end-locking), including illustrations and tables for Type B1 (end‑locking) and Type B2 (centre‑locking with locking ring).
• Dimensions: Standardized diameters and lengths are given in the document’s figures and tables; surface roughness indications and optional features (lifting threads, central holes) are shown. Typical diameters cited include 25 mm up to 160 mm (see Tables 1 & 2).
• Tolerances: Tolerance classes and limit deviations reference ISO 286‑2; example tolerance grade used in designation is f6.
• Material & hardness: Material selection is at the manufacturer’s discretion, but the pillar hardness shall be 56 HRC (Rockwell C) as defined by ISO 6508‑1.
• Designation format: Prescribed naming includes the words “Guide pillar”, reference to ISO 9182‑3:2023, type (B1 or B2), diameter with tolerance, overall length and option code (A or B) to indicate presence/absence of central hole or thread. Example:
  Guide pillar ISO 9182–3 – B1 – 25f6 × 125 – B
• Referenced features: Centre holes/representation per ISO 6411; drawing and tolerance conventions per ISO technical directives.

Applications

• Standardizes guide pillar components used in:
  • Die and press tool assemblies (stamping, forming)
  • Injection moulding and press mould guides
  • Repair, replacement and interchangeability of guide pillars in production tooling
• Ensures interchangeability, consistent performance, predictable wear and simplified procurement for tooling shops and OEM tool manufacturers.

Who should use this standard

• Tool designers and die makers
• Production engineers and maintenance teams in stamping/moulding industries
• Quality engineers and metrology teams verifying dimensions and hardness
• Procurement specialists specifying standard components for press tools
