After inquiries and votes carried out in accordance with the rules of this
19、Association, this standard has successively received the approval of the National Associations and the Official Services of the member countries of AECMA, prior to its presentation to CEN. This standard was submitted for Formal Vote, and the result was positive. This European Standard shall be given
20、 the status of a national standard, either by publication of an identical text or by endorsement, at the latest by December1994, and conflicting national standards shall be withdrawn at the latest by December1994.

22、ingle row ball bearings in corrosion resisting steel of diameter series0 and2 1)designed to withstand only slow rotations and oscillations under load. They are intended for use between fixed and moving parts of the aircraft structure and their control mechanisms. The airframe rolling bearings define
23、d in this standard are used from54 C to+150 C. However, being lubricated with the following greases: very high pressure grease, ester type (code A), operational range73 C to+121 C or very high pressure grease, synthetic hydrocarbons, general purpose (code B), operational range54 C to+177 C (seeEN328
24、0), their field of application when lubricated with code A grease is limited to+121 C. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications.
