TS ISO 6811/Cor 1

TS ISO 6811/Cor 1 is Technical Corrigendum 1 to TS ISO 6811:1998 for spherical plain bearings. It focuses on the vocabulary used in this field, helping align terms and definitions for bearings, bearing parts, movement and angle concepts, and rod ends.

What this vocabulary standard covers

Spherical plain bearings are machine elements designed to accommodate angular misalignment while supporting oscillating or rotational movement. Vocabulary standards do not define a product’s performance requirements; they organise the language used to describe that product family. In this case, the standard addresses the general terminology associated with bearings, bearing parts, features, movements, angles and rod ends, so the same technical concepts are understood consistently across documents and organisations.

Why a corrigendum matters

A corrigendum is a technical correction to an existing standard, not a separate requirement standard with its own test methods or limits. Here, the value lies in clarifying and stabilising terminology for engineering communication. That is especially useful in drawings, catalogues, procurement specifications, maintenance documents and product descriptions where precise wording helps avoid ambiguity.

• Associated bearing parts and construction features
• Movement- and angle-related terms
• Rod end terminology within the same vocabulary framework
