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.
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.
International Standard ISO 13415 was prepared by Technical Committee ISO/TC 20, ,
Aircraft and space vehicles
Subcommittee SC 15, .

Introduction
At the time this International Standard was developed, the Imperial units sizes of airframe needle roller bearings were
dominant in world application. The basis for this International Standard is the imperial units provided in annex A.

INTERNATIONAL STANDARD  ISO ISO 13415:1997(E)
Aerospace — Airframe needle track roller, stud type, single-row,
sealed — Inch series
1 Scope
This International Standard specifies the characteristics, boundary dimensions, tolerances, internal clearances and
permissible static radial loads of inch series, single-row, stud type needle track rollers used in airframe applications.
The airframe needle track rollers covered by this International Standard are designed to operate in the temperature
range –54 °C to +121 °C.
2 Normative references
The following standards contain provisions which, through reference in this text, constitute provisions of this
International Standard. At the time of publication, the editions indicated were valid. All standards are subject to
revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility
of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of

7 Surface treatment
 Bearings made of conventional rolling bearing steel shall have the external surfaces of the outer ring chromium
7.1
plated, and all other external surfaces cadmium or zinc-nickel plated.
7.2 Where cadmium plating is specified (code letters D and M), it shall be in accordance with ISO 2082. The thickness
of the plating shall not be less than 7 μm and not more than 15 μm. The bearing shall be embrittlement-relieved within
