ISO 3547-1:2006(E)
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 in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. 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.
ISO 3547-1 was prepared by Technical Committee ISO/TC 123, Plain bearings, Subcommittee SC 3,
Dimensions, tolerances and construction details.
This second edition cancels and replaces the first edition (ISO 3547-1:1999), 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
The following parts are under preparation:
⎯ Part 5: Checking the outside diameter
⎯ Part 6: Checking the inside diameter
⎯ Part 7: Measurement of wall thickness of thin-walled half-bearings and thin-walled bushes

See Figure 1 and Tables 2 to 4.
The largest dimension of the inside diameter of the bush in its pressed-in condition is obtained from the
largest dimension of the bore in the housing minus twice the smallest dimension of the wall thickness, s . The
3
smallest dimension of the inside diameter of the bush in its pressed-in condition can be obtained from the
smallest dimension of the bore in the housing minus twice the greatest dimension of the wall thickness, s .

This assumes that there is no expansion of the bore in the housing caused by pressing in the bush. In reality,
the expansion depends on several factors, such as the stiffness of the housing and the bush. An example of
the calculation is given in Clause 7.
The wall thickness limit deviation depends on whether or not there is a machining allowance in the bush bore
and on the material type, as specified in ISO 3547-4. The preferred limit deviation series (A to E) is specified
in Table 5.
Instead of the wall thickness, the inside diameter, D , of the bush may be specified. D is the inside
i, ch i, ch
diameter of the bush, when this is pressed into a ring gauge (Test C — gauging — in accordance with
ISO 3547-2:2006, see also ISO 3547-6).

For bushes which are supplied with a machined bore (Series W), the limit deviations of the inside diameter of
the bush, D , checked in a ring gauge, are given in Table 6.
i, ch
In no case shall wall thickness and inside diameter be given at the same time as the dimensions that are to be
checked.
The tolerance for the inside diameter, D , of the bush in the ring gauge is given in Table 6. The tolerance of
i, ch
the inside diameter of a bush pressed into a housing is found from the sum of the tolerance for, D , and the
i, ch
tolerance of the housing bore. As in the case of the calculation of the inside diameter from the wall thickness,
it is assumed that there is no expansion of the housing bore.
Dimensions for the outside diameter, D , of the bush are given in Table 7.
