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 13416 was prepared by Technical Committee ISO/TC 20, ,
Aircraft and space vehicles
Subcommittee SC 15, .

INTERNATIONAL STANDARD  ISO ISO 13416:1997(E)
Aerospace — Airframe needle track roller, yoke type, single-row,

1 Scope
This International Standard specifies the characteristics, boundary dimensions, tolerances, internal clearances and
permissible radial static loads of metric series, single-row, yoke 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.

9 Designation
Bearings covered by this International Standard shall be designated only as in the following example:
where the following codes are applied:
— greases:
A = ester type grease;
B = synthetic hydrocarbon type grease;
— materials/surface treatments:

inner ring - cadmium plated with chromate conversion coating, or black oxide coated;
M = material: low alloy bearing steel;
surface treatment: outer ring - chromium plated;
