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 4383 was prepared by Technical Committee ISO/TC 123, Plain bearings, Subcommittee SC 2, Materials
and lubricants, their properties, characteristics, test methods and testing conditions.
This fourth edition cancels and replaces the third edition (ISO 4383:2000), which has been
technically revised.

INTERNATIONAL STANDARD ISO 4383:2012(E)
Plain bearings — Multilayer materials for thin-walled
plain bearings
1 Scope
This International Standard specifies requirements for multilayer materials for the manufacture of
thin-walled plain bearings (half bearings, bushes, thrust washers). The multilayer material consists
of a steel backing, the bearing layer (cast, sintered, roll bonded) and, possibly, an overlay. The chemical
composition refers to the original unprocessed material and is intended to be measured on representative
samples. Testing results on final bearings can be due to the influence of bearing production. Therefore,
these results cannot be compared with data given in this International Standard.
NOTE Environmental concerns will, in the future, restrict the use of some materials such as lead.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
ISO 4381, Plain bearings — Tin casting alloys for multilayer plain bearings
ISO 4382-1, Plain bearings — Copper alloys — Part 1: Cast copper alloys for solid and multilayer thick-
walled plain bearings
ISO 6691, Thermoplastic polymers for plain bearings — Classification and designation
ISO 6280, Plain bearings — Requirements on backings for thick-walled multilayer bearings
3 Requirements
3.1 Chemical composition
The chemical composition of alloy elements shall be within the limits specified in Tables 1 to 5.
3.2 Steel backings
The chemical composition of the steel for backings shall be the subject of agreement between the
manufacturer and purchaser. In general, low carbon steel is used.
For bronze/polymer composite materials listed in Table 4, copper-coated steel may be used. Backings
shall conform to ISO 6280.
3.3 Bearing layers
Bearing metals based on tin shall be in accordance with Table 1.
Bearing metals based on copper shall be in accordance with Table 2.
Bearing metals based on aluminium shall be in accordance with Table 3.
Bearing layers based on sintered porous bronze and polymers shall be in accordance with Table 4.
NOTE There is a new class of aluminium-based materials containing both aluminium and silicon or manganese
as well as a “soft” material, such as lead or tin. Detailed information is available from individual manufacturers.
3.4 Overlays
Overlays in accordance with Table 5 may be applied for bearing metal layers as indicated in Table A.2.
The thickness of the overlay and any additional layers between the bearing metal layer and the overlay
shall be the subject of
