Описание (английский):

This document specifies the boundary dimensions and normal class tolerance values for needle roller bearings with machined rings. This document specifies dimensional and geometrical characteristics, and limit deviations from nominal sizes. These specifications apply to complete needle roller bearings and to bearings without inner ring.

Overview

ISO 1206:2023 - Rolling bearings - Needle roller bearings with machined rings - Boundary dimensions, geometrical product specifications (GPS) and tolerance values defines the geometric and dimensional framework for needle roller bearings with machined rings. This fifth edition (2023) replaces ISO 1206:2018 and applies to both complete needle roller bearings and bearings without inner ring. It is a machine-element geometry standard within the GPS system and links functional requirements to measurement and verification practice.

Key topics and technical requirements

Boundary dimensions and chamfers: nominal sizes and maximum chamfer dimensions are specified using standard dimension series (Tables 2–7) derived from ISO 15 and ISO 582.

Geometrical product specifications (GPS): symbols, specification modifiers and GPS rules are defined (see Table 1 and Figures 1–2) for two-point size, mid-range sizes and other GPS characteristics.

Tolerance values: normal-class tolerance values and limit deviations from nominal sizes for complete bearings and bearings without inner ring (Section 6).

Radial internal clearance: guidance on clearance classes and characteristic definitions (Section 7).

Symbols and terms: mappings to previous editions and GPS terminology (Annex B); note the symbol change ΔFwgn introduced in this edition.

Measurement and verification: Annex C provides guidelines for measurement techniques and verification methods - aligning specifications with measurement uncertainty practices.

Informative guidance: Annex A recommends tolerances for shaft raceways used with needle roller bearings without inner ring.

Normative references and GPS context: the standard references ISO 1101, ISO 5593, ISO 14405‑1, ISO/TS 17863 and follows GPS rules per ISO 8015 and decision rules of ISO 14253‑1 (measurement uncertainty per ISO 14253‑2).

Practical applications

Ensure interchangeability and consistent fit between needle roller bearings and mating components.

Provide design engineers with standard boundary dimensions and chamfer limits for CAD, drawings and BOMs.

Support manufacturing and quality engineers in setting inspection criteria, specifying tolerance classes and planning metrology.

Aid procurement and OEMs in verifying supplier parts conform to internationally recognized GPS and tolerance values.

Guide maintenance and retrofitting where replacement bearings (with or without inner rings) must meet defined geometrical limits.
