Full title and description

ISO 10317:2008/Amd 1:2013 — Rolling bearings — Tapered roller bearings — Designation system — Amendment 1: Design variant designation and comparison of tolerance class designations for single-row tapered roller bearings. This amendment is issued as a supplement to ISO 10317:2008 and is available in PDF and print formats in English and French.

Abstract

ISO 10317:2008 establishes a system for the designation of metric-size tapered roller bearings manufactured in accordance with ISO 355, covering single-row, double-row and bearings with flanged outer rings, and designations for separate inner subunits and outer rings. Amendment 1 (2013) adds a design-variant designation and provides a comparison of tolerance-class designations for single-row tapered roller bearings.

Scope

This amendment applies to ISO 10317:2008 and introduces a designation for design variants and a comparison of tolerance-class designations specifically for single-row tapered roller bearings. The underlying ISO 10317 system covers designation formats for single-row, double-row, and flanged-outer-ring tapered roller bearings and for separate inner subunits and outer rings produced to ISO 355; bearings that deviate from ISO 355 are outside the scope.

Key topics and requirements

• Standardized designation system for metric tapered roller bearings (single-row, double-row, flanged outer rings).
• Designation rules for separate inner subunits (inner ring, tapered rollers and cage) and outer rings.
• Addition of a design-variant designation to clarify alternative constructions and subunit configurations introduced by Amendment 1 (2013).
• Comparison and mapping of tolerance-class designations for single-row tapered roller bearings to support interchangeability and procurement.
• Requirement that the designation system applies only to bearings manufactured in accordance with ISO 355 (exceptions are excluded).

Typical use and users

Mechanical and design engineers, bearing manufacturers, procurement and quality teams, maintenance and reliability engineers, technical libraries and standards coordinators use ISO 10317:2008 together with Amendment 1 when specifying, ordering or documenting tapered roller bearings to ensure consistent designation, correct interpretation of tolerance classes, and interchangeability of components.

FAQ

Q: What is this standard?

A: ISO 10317:2008/Amd 1:2013 is Amendment 1 (2013) to ISO 10317:2008, the international designation system for metric tapered roller bearings; the amendment adds a design-variant designation and a comparison of tolerance-class designations for single-row tapered roller bearings.

Q: What does it cover?

A: It covers the rules and codes used to designate tapered roller bearings (single-row, double-row, flanged outer rings) and their separate inner and outer subunits, and — through the amendment — clarifies design-variant notation and tolerance-class comparisons for single-row bearings manufactured to ISO 355.

Q: Who typically uses it?

A: Bearing designers and manufacturers, procurement/specification engineers, quality/control departments, maintenance and reliability teams, and standards bodies use this standard to ensure unambiguous identification and interchangeability of tapered roller bearings and their components.

Q: Is it current or superseded?

A: The amendment was published in 2013 as ISO 10317:2008/Amd 1:2013 and applies to ISO 10317:2008. The base standard has been maintained and reviewed by ISO; users should check ISO or their national standards body for the latest confirmation or any further revisions beyond 2013.

Q: Is it part of a series?

A: Yes — it is an amendment to ISO 10317:2008; ISO 10317 itself is part of the family of ISO standards dealing with rolling bearings and references ISO 355 for dimensional and manufacturing requirements of metric tapered roller bearings.

Q: What are the key keywords?

A: Tapered roller bearings, designation system, ISO 10317, amendment 2013, design variant, tolerance classes, ISO 355.
