After inquiries and votes carried out in 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 to CEN.

19、 This standard was submitted for Formal Vote, and the result was positive. This European Standard shall be given the status ofa 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of an identical text or by endorsement, at the latest by October1994, and conflicting national standards shall be withdrawn at the

20、latest by October1994.

21、, United Kingdom.EN3058:1994 BSI 01-2000 3 1 Scope This standard specifies the characteristics of rigid double row ball bearings in corrosion resisting steel designed to withstand only slow rotations and oscillations under load. They are intended for use in the hubs of bell crank levers fitted with

22、a single bearing. 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 range73 C to+121 C or very high pressure grease, synthetic hydrocarbons, general purp

23、ose (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 cit

24、ed at the appropriate places in the text and the publications are listed hereafter.
