The work of preparing Inte
5、rnational 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 wi
6、th 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 a
7、n International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 14204 was prepared by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcommittee SC 15, Airframe bearings.

9、meter series 0 Metric series 1 Scope This International Standard specifies the characteristics, boundary dimensions, tolerances, internal clearances and permissible loads of metric series double-row, rigid, ball bearings of diameter series 0, in accordance with ISO 15, used in airframe applications.
10、 These bearings are full complement (without cage) with a double row of balls and filling slot. These bearings are designed to withstand only slow rotations and oscillations under load and are intended for use between fixed and moving parts of an aircraft structure and their control surfaces. The ai
11、rframe ball bearings covered by this International Standard are designed to operate in the temperature range of 54 C to + 150 C. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time
12、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.
