Full title and description

ISO 6811:1998 — Spherical plain bearings — Vocabulary. This International Standard defines general terms and definitions related to spherical plain bearings, their components, movements, angles and rod ends; the publication is available in the ISO official languages including Russian.

Abstract

This standard provides a consistent vocabulary for the field of spherical plain bearings to ensure clear communication between designers, manufacturers, users and standards bodies. It lists terms for bearing types, bearing parts and features, movements and angles, and specific terminology for rod ends. The document also includes equivalent German terms published separately by DIN while the ISO authoritative terms are given in English, French and Russian.

Scope

ISO 6811:1998 defines and describes the terminology used for spherical plain bearings — including radial, angular-contact and thrust types — their constituent parts, features, permissible movements, test-related angles and the terminology used for rod ends. The scope is limited to vocabulary and does not specify dimensions, performance requirements or test methods.

Key topics and requirements

• Standardized definitions for spherical plain bearing types and subtypes (radial, angular contact, thrust) and their components.
• Terms describing geometrical features, movements (tilt, rotation, oscillation) and angles relevant to bearing function.
• Vocabulary for rod ends (bearing housings with threaded shanks) and related connection terminology.
• Clarification that equivalent German terms are provided under DIN responsibility, while only the official ISO languages’ terms are normative.
• Technical corrigendum issued in July 1999 to correct and clarify selected entries (ISO 6811:1998/Cor 1:1999).

Typical use and users

Used by bearing manufacturers, mechanical designers, procurement and maintenance engineers, technical translators and standards librarians to ensure consistent terminology in product specifications, design documents, procurement contracts, technical training and translations. It is also a reference for test and inspection personnel and for national standardization bodies when aligning local terminology with ISO usage.

Related standards

ISO 6811 is part of the body of ISO work on plain and spherical bearings and is commonly used alongside dimensional and performance standards such as the ISO 12240 series (spherical plain bearings and rod ends), calculation and load-rating methods (e.g., ISO 20015), and more recent rod-end and hydraulic-cylinder related documents (for example ISO 24652:2023). These related standards cover dimensions, tolerances, load ratings and specific application requirements.

FAQ

Q: What is this standard?

A: ISO 6811:1998 is an ISO International Standard that provides a standardized vocabulary for spherical plain bearings and related components to ensure consistent terminology across design, manufacture and use.

Q: What does it cover?

A: It covers terms and definitions for spherical plain bearings, bearing parts and features, allowable movements and angles, and terminology for rod ends; it is strictly a vocabulary/terminology standard and does not set dimensional or performance requirements.

Q: Who typically uses it?

A: Bearing manufacturers, mechanical designers, procurement and maintenance engineers, test/inspection personnel, technical translators and standards organizations use it as a reference for correct and consistent terminology.

Q: Is it current or superseded?

A: The 1998 edition (Edition 2) is the current published edition; it was reviewed and confirmed in later ISO systematic reviews and remains published. A technical corrigendum was issued in July 1999 (ISO 6811:1998/Cor 1:1999) to correct specific entries.

Q: Is it part of a series?

A: Yes — ISO 6811 provides vocabulary used across the family of ISO standards on spherical plain bearings; it is commonly referenced together with dimensional and application standards such as the ISO 12240 series (parts for radial/ angular/ thrust bearings and rod ends) and calculation/performance standards like ISO 20015 and more recent application-specific standards (e.g., ISO 24652).

Q: What are the key keywords?

A: Spherical plain bearing, vocabulary, terminology, rod end, plain bearing, bearing parts, tilt angle, ISO.
