Full title and description

Rolling bearings — Needle roller bearing track rollers — Boundary dimensions, geometrical product specifications (GPS) and tolerance values. This International Standard defines the nominal boundary dimensions, dimensional characteristics and tolerance values used for needle roller track rollers (yoke and stud types) to ensure interchangeability and consistent product specification.

Abstract

This document specifies dimensional characteristics, nominal boundary dimensions and tolerance values for needle roller bearing track rollers, covering yoke and stud types and applying GPS (geometrical product specification) principles for dimensions and tolerances.

Scope

Specifies the boundary (envelope) dimensions, dimensional characteristics, GPS-compatible tolerancing rules and numerical tolerance values for needle roller bearing track rollers of the yoke and stud types. The standard defines terms, symbols and the measurement/tolerance framework required for design, manufacture and inspection to achieve interchangeability of track rollers in applications such as linear guidance, cam followers and conveyor systems.

Key topics and requirements

• Defined nominal boundary (envelope) dimensions for needle roller track rollers (yoke and stud types).
• Geometrical product specification (GPS) principles for dimensional tolerancing and symbols.
• Numeric tolerance values and tolerance classes applicable to the specified dimensions.
• Terms, definitions and symbols needed for unambiguous specification and inspection.
• Guidance to ensure interchangeability between manufacturers and to support CAD/modeling and inspection planning.

Typical use and users

Used by bearing and component manufacturers, mechanical and design engineers, procurement/specification teams, metrology and quality departments, and OEMs to specify, produce and verify needle roller track rollers. It is applied in product design, acceptance criteria, inspection procedures and procurement documentation for linear motion systems, cam followers, conveyors and other rolling-contact assemblies.

Related standards

Supersedes ISO 7063:2003 and earlier editions (ISO 7063:1982); related GPS and dimensional-tolerancing standards commonly used alongside ISO 7063 include ISO 1101 (geometrical tolerancing), ISO 14405‑1 (dimensional tolerancing) and broader rolling-bearing GPS standards such as ISO 492 and ISO 281 for other bearing types. The standard is developed under ISO/TC 4/SC 5 (rolling bearings).
