After inquiries and votes carried out in accordance with the rules of this Association, this
19、standard has successively received the approval of the National Associations and the Official Services of the member countries of AECMA, prior to its presentation toCEN. This standard was submitted to the Formal Vote and the result was positive. This European Standard shall be given the status ofa n
20、ational 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of an identical text or by endorsement, at the latest by December1994 and conflicting national standards shall be withdrawn at the latest by December1994. According to the CEN/CENELEC Internal Regulations, the following countries are bound toimplement this Eur

22、ler bearings in corrosion resisting steel of diameter series3 and4 1)designed to withstand only slow rotations, oscillations and/or swivelling under load. They are intended for use between fixed and moving parts of the aircraft structure and their control mechanisms. The airframe rolling bearings de
23、fined 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 (see
24、EN3280), 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.
