Overview

ISO 12240-4:1998/Cor 1:1999 is a technical corrigendum to the international standard ISO 12240-4:1998, which covers spherical plain bearing rod ends. Published by ISO/TC 4 (Rolling bearings), Subcommittee SC 7 (Spherical plain bearings), this corrigendum issues a targeted correction to dimensional data in Table 3 of the original Part 4 document. The correction affects the radius values for the nominal bore size d = 20 mm, ensuring the published dimensions are accurate for design, manufacture and inspection.

Key topics and corrections

• Scope: Applies to the dimensional specification and related tabulated data for spherical plain bearing rod ends (Part 4).
• Technical Corrigendum summary:
  • In Table 3 for d = 20 mm, two radius values were incorrect in the original publication and have been corrected:
    • One radius value should be 0.3 mm (previously listed as 0.6 mm).
    • The other radius value should be 0.6 mm (previously listed as 0.3 mm).
  • Effectively, the two radius entries for d = 20 mm are swapped to the correct values.
• Implications:
  • Correct geometric data is essential for interchangeability, correct assembly, fatigue life and proper seating of rod ends.
  • The corrigendum provides the authoritative fix for manufacturers, designers and quality inspectors referencing ISO 12240-4.

Practical applications and users

• Design engineers: Use the corrected dimensions when specifying spherical plain bearing rod ends in mechanical linkages, steering systems, suspension components and motion-control assemblies.
• Bearing manufacturers: Apply the corrigendum to tooling, inspection plans and production tolerances to ensure parts conform to the ISO specification.
• Quality and procurement teams: Rely on the corrected standard for acceptance criteria, drawing notes and supplier verification.
• Maintenance and service engineers: Refer to standard dimensions when replacing rod ends to ensure proper fit and function.

Related standards and context

• ISO 12240 is a multipart standard series covering various types of spherical plain bearings; Part 4 focuses specifically on rod ends.
• Other ISO/TC 4 outputs (rolling bearings standards) and national standards on bearing dimensions and tolerances are commonly used alongside ISO 12240-4 for comprehensive specification and quality control.
