ISO 12240 is the standard cited for rod end bearing. This page sets out what the standard controls for this part, reproduces the dimensional table supplied against it, and notes the related designations referenced on drawings.
ISO 12240 — Scope
The table below lists the dimensions catalogued for rod end bearing — iso / din (series 106) under ISO 12240. The scope of ISO 12240 itself is not summarised here — where a figure matters, confirm it against the published document.
Tolerance & Product Grades
Product grade is a concept from dimensional fastener standards and does not apply to ISO 12240. Tolerances for this part are the limits shown against each dimension in the table.

Companion Standards
A complete specification for rod end bearing — iso / din (series 106) normally cites several documents: one for the geometry, one for the material or mechanical properties, and one for the finish. ISO 12240 is one of them, not all of them.
When to Specify ISO 12240
Choose ISO 12240 for international engineering work and OEM supply where ISO standards are the contractual reference. It is the default modern specification for rod end bearing — iso / din (series 106).
Custom manufacturing · Made to drawing
Need a bearing & bushing to this standard in a non-standard size?
Parts built to ISO 12240 are already in the catalog, so a special is usually a variation on existing tooling rather than a new design — which is what keeps the cost down.
Minimum order from 2,000 pieces; samples within 7 days of drawing approval.
