Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted according to the rules given in the ISO/IEC Directives, Part 2.
Draft International Standards adopted by the technical committees are circulated to the member bodies for
voting. Publication as an International Standard requires approval by at least 75 % of the member bodies
casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 3547-5 was prepared by Technical Committee ISO/TC 123, Plain bearings,
Subcommittee SC 5, Quality analysis and assurance.
This part of ISO 3547 cancels and replaces ISO 12307-1:1994, which has been technically revised.
ISO 3547 consists of the following parts, under the general title Plain bearings — Wrapped bushes:
⎯ Part 1: Dimensions
⎯ Part 2: Test data for outside and inside diameters
⎯ Part 3: Lubrication holes, grooves and indentations
⎯ Part 4: Materials
⎯ Part 5: Checking the outside diameter
⎯ Part 6: Checking the inside diameter
⎯ Part 7: Measurement of wall thickness of thin-walled bushes

INTERNATIONAL STANDARD ISO 3547-5:2007(E)

Plain bearings — Wrapped bushes —
Part 5:
Checking the outside diameter
1 Scope
This part of ISO 3547 specifies, following ISO 12301, the checking of the outside diameter of wrapped bushes
(ISO 3547-2:2006, methods A, B and D) and describes the necessary checking methods and measuring
equipment.
Wrapped bushes in the free condition are flexible, but after insertion they adapt largely to the shape of the
housing bore due to the oversize between the outside diameter of the bush and the housing bore. For this
reason, checking of the outside diameter of wrapped bushes can only be carried out under a constraining load
by use of specialized measuring equipment.
NOTE 1 The dimensions and tolerances of wrapped bushes are given in ISO 3547-1. Checking the wall thickness is
the subject of ISO 3547-7.
2 Normative references

references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.

5 Purpose of checking
The outside diameter shall be checked to ensure the designated mounting compression (interference fit) for
the wrapped bush in the housing bore.
6 Methods of checking
NOTE Checking method C is for measuring the inside diameter and is covered by ISO 3547-6.
6.1 Checking method A — Measurement of outside diameter, D
o
NOTE See ISO 3547-2.
Check the outside diameter of a wrapped bush using measuring equipment as shown in Figure 2, with a
checking block consisting of upper and lower halves (see Figures 3 and 4) and setting plugs (see Figures 5
and 6), at a determined checking load, F .
ch
Measure the outside diameter indirectly as the difference in the value of z, ∆z.
The checking load is calculated so that the bush outside diameter is reduced only elastically during checking
and that there is no permanent deformation.
6.2 Checking method B — Gauging of outside diameter, D
o
NOTE See ISO 3547-2.
Check the outside diameter of a wrapped bush in “GO” and “NO GO” ring gauges.
6.3 Checking method D — Measurement of outside diameter, D > 120 mm
o
NOTE See ISO 3547-2.
Check the outside diameter of a wrapped bush above 120 mm diameter using a precision measuring tape.
7 Selection of checking method for outside diameter
Method A is a precise method involving complex tooling. Method B is an attributive method using simpler
tooling. Method D is used only for wrapped bushes with an outside diameter > 120 mm. All three methods are
in general use. Method A is generally unsuitable for small bushes up to 10 mm outside diameter but is
preferred for bushes over 10 mm outside diameter.
8 ISO 3547-2, test A — Outside diameter, D
o
8.1 Measuring equipment
See Tables 2 and 3.
Typical equipment for measuring the bush consists essentially of the following components:
⎯ base plate used as fixture and guiding device for the split checking block;
⎯ means to generate the checking load;
⎯ means to calibrate the load;

⎯ upper plate;
⎯ system for transmitting the distance, z, of both checking block halves to the measuring pin (see Figure 2);
⎯ measuring pin with indicating instrument;
⎯ checking block (see Figures 3 and 4) with setting plug (see Figures 5 and 6).
