5、ndards 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 or
6、ganizations, 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
7、 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.

9、E) 1 Aerospace Airframe spherical roller bearings, single-row, self-aligning, shielded, intermediate duty Metric series 1 Scope This International Standard specifies the characteristics, boundary dimensions, tolerances, internal clearances and permissible loads of metric series single-row, self-alig
10、ning, shielded, intermediate duty spherical roller bearings used in airframe applications. 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 airfram
11、e roller 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.
