Overview

ISO 3547-6:2020 - Plain bearings - Wrapped bushes - Part 6: Checking the inside diameter - specifies accepted methods and measuring equipment for checking the inside diameter of wrapped bushes. Following ISO 12301 and referring to ISO 3547-2 (method C), this standard explains how to transform a flexible free bush into a measurable condition (by pressing it into a ring gauge) and how to determine the inside diameter using mechanical gauges or measuring instruments. All dimensions are given in millimetres unless otherwise noted.

Key topics and requirements

Purpose: Because wrapped bushes are flexible, the free diameter is not measured directly; the bush is pressed into a ring gauge whose nominal diameter corresponds to the housing bore (typically H7 tolerance).

Measuring methods:

Three-point measuring instrument (radial measurement using spherical pin faces).
GO / NO-GO plug gauges: GO plug should insert with minimum effort; NO-GO must not insert under a maximum force (standard default 250 N, but the limit may be agreed between supplier and user).
Alternative methods (subject to correlation): cylindrical gauges, dial gauges, optical devices.

Test equipment:

Ring gauge and plug gauge dimensions and wear limits specified (see standard tables).
Gauges must be made from hardened, non-ageing steel (60–64 HRC).

Measurement considerations and error sources:

Damage/wear to ring or plug gauges, lack of lead-in chamfer, misalignment during insertion, insufficient ring width, contaminants (grease, burrs), and swelling of parts.

Agreement between supplier and user:

Decide whether results are recorded by measuring or by gauging, and agree on any force limits, special dimensions (for D > 180 mm), or deviations from default gauges.

Applications and users

Who uses ISO 3547-6:2020:

Quality engineers and inspection technicians in bearing and bush manufacturing.

Metrology and QA teams in automotive, industrial machinery, hydraulic and pivot applications where wrapped bushes are used.

Suppliers and purchasers negotiating inspection protocols and acceptance criteria.

Practical benefits:

Ensures consistent, reproducible inside-diameter checks across suppliers and users.

Reduces measurement disputes by defining gauges, wear limits and common error sources.

Integrates with plant quality-control procedures (ISO 12301) for geometrical inspection.
