After inquiries and votes carried out in
18、 accordance with the rules of this 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 toCEN. This standard was submitted for Formal Vote, and the result was positive. Thi
19、s European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by October1994, and conflicting national standards shall be withdrawn at the latest by October1994. According to the CEN/CENELEC Internal Regulations, the
20、 following countries are bound to implement this European Standard: Austria, Belgium, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland, UnitedKingdom.EN3053:1994 BSI 01-2000 3 1 Scope This standard specifies the
21、 characteristics of single row self-aligning roller bearings in steel 1)designed to withstand only slow rotations, oscillations and/or swivelling under load. They are intended for use in bell crank lever ends or at the end of rigid flight control rods for transmission purposes, before or after servo
22、 operation. The airframe rolling bearings defined 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 range 73 C to+121 C or very high pressure grease, synthetic hydrocarbons, general purpose (
23、code B), operational range54 C to+177 C (seeEN3280), 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. These normative references are cited a
