Full title and description

ISO 10317:2008 — Rolling bearings — Tapered roller bearings — Designation system. This International Standard establishes a system for the designation of metric-size tapered roller bearings manufactured in accordance with ISO 355, including designations for single-row, double-row and flanged-outer-ring bearings, and for separate inner subunits and outer rings.

Abstract

ISO 10317:2008 specifies the structure and rules used to form designation codes for metric tapered roller bearings (and their inner subunits and outer rings) produced to ISO 355, enabling consistent identification across manufacturers, purchasers and standards documents. The standard excludes bearings or subunits that deviate from ISO 355.

General information

• Status: Published — International Standard (confirmed in systematic review 2023).
• Publication date: November 2008 (Edition 2, 2008).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 21.100.20 — Rolling bearings.
• Edition / version: Edition 2 (2008).
• Number of pages: 5 pages (main publication).

Scope

Defines a designation system for metric tapered roller bearings produced in accordance with ISO 355, covering single-row, double-row and bearings with flanged outer rings, and providing designations for inner subunits (inner ring, tapered rollers and cage) and for outer rings. The standard does not apply to bearings or components that deviate from ISO 355.

Key topics and requirements

• Designation format and structure for metric tapered roller bearings (bore/size series, design variant, tolerance class and sub-unit prefixes).
• Designation rules for single-row, double-row and flanged-outer-ring bearings.
• Designation of separate inner subunits (inner ring, tapered rollers and cage) and outer rings.
• Amendment 1 (2013) — adds/clarifies design variant designation and provides comparison of tolerance-class designations for single-row tapered roller bearings.
• Exclusion: bearings or components that in any respect deviate from ISO 355 are not covered.

Typical use and users

Used by bearing designers and manufacturers, procurement and quality teams, mechanical and rotating-equipment engineers, standards committees and technical libraries to ensure unambiguous identification and ordering of metric tapered roller bearings and their components.

Related standards

FAQ

Q: What is this standard?

A: ISO 10317:2008 is an International Standard that defines the designation system used to identify metric tapered roller bearings and their sub-units produced in accordance with ISO 355.

Q: What does it cover?

A: It covers the structure and rules for forming designation codes for single-row, double-row and flanged-outer-ring tapered roller bearings, and for separate inner subunits and outer rings; it excludes bearings that deviate from ISO 355.

Q: Who typically uses it?

A: Bearing manufacturers, mechanical and design engineers, procurement and quality assurance personnel, and standards/technical committees use this standard to ensure consistent identification, ordering and documentation of tapered roller bearings.

Q: Is it current or superseded?

A: The 2008 edition (Edition 2) remains the current published version and was last confirmed in ISO’s systematic review process in 2023; it is also amended by ISO 10317:2008/Amd 1:2013.

Q: Is it part of a series?

A: Yes — it belongs to the family of ISO rolling-bearing standards (ICS 21.100.20) maintained by ISO/TC 4/SC 5 and is functionally linked to ISO 355 and other rolling-bearing standards and technical reports.
