TS ISO 5593

TS ISO 5593 is a vocabulary standard for rolling bearings, setting out the terms used in this technical field together with their definitions. Its role is to give designers, manufacturers, cataloguers and technical writers a common language for the key concepts of bearing technology. The document is focused on terminology; it is not a performance, calculation or test standard.

What the vocabulary covers

The standard covers terms connected with all types of rolling bearings in which continuous rotation about an axis is enabled by an ordered set of rolling elements between two circular raceways, allowing loads to be transmitted in radial and/or axial directions. Accessories associated with these products are also included. In general technical terms, this kind of vocabulary standard helps distinguish the main bearing parts and functional concepts so that the same words are used consistently across design, production and documentation.

What is not included

• Terms specified in ISO 76, ISO 281 and ISO 1132-1 are excluded from this document.
• Terms that are used narrowly in only one specialised rolling bearing International Standard are also excluded.
• This keeps the vocabulary centered on broadly applicable terminology rather than application-specific or calculation-specific wording.

As a result, TS ISO 5593 serves as a foundational reference for anyone who needs consistent terminology in rolling bearing technology, including engineering teams, quality functions and technical documentation work. Standardised vocabulary reduces ambiguity and makes it easier to communicate clearly about bearing construction, function and accessories.
