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 19349 was prepared by Technical Committee ISO/TC 123, Plain bearings, Subcommittee SC 3,

Dimensions, tolerances and construction.

Plain bearings — Lubrication and lubrication monitoring
1 Scope

This standard specifies requirements for oil-lubricated plain bearings (plain bearing assemblies) as for

instance specified in ISO 11687.
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 11687(all parts), Pedestal plain bearings;
3 Lubricants

Hydrodynamic plain bearings can be operated with lubricants of different chemical bases. For the guidelines

given hereafter, lubrication using oils from a petroleum base (mineral oil) is assumed. Synthetic lubricants

might also be used. The bearing manufacturer shall be asked for acceptable classes of lubricants (ISO 6743-

99).
Lubricant viscosity grade (ISO 3448) is typically between ISO
