This 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of an identical text or by endorsement, at the latest by December 2007, and conflicting national standards shall be withdrawn a
14、t the latest by December 2007. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. According to the CEN/CENELEC Internal Regulations, the

EN 3059:20074 1 Scope This standard specifies the characteristics of rigid single row ball bearings in steel, with cadmium-plated flanged alignment housing designed to withstand only slow rotations
17、and oscillations under load. They are intended for use in the hubs of torsion lever and in separated supports for airframe/aerospace applications. The airframe rolling bearings defined in this standard may be used in the temperature range from 54 C to 150 C. However, being lubricated with the follow
18、ing greases (see EN 3727): ester type very high pressure grease (code letter A), operating range from 73 C to 121 C or, synthetic hydrocarbons type very high pressure grease general purpose (code letter B) operating range from 54 C to 177 C. Their field of application when lubricated with code lette
19、r A grease is limited to 121 C. 2 Normative references The following referenced documents are indispensable for the application of this document.
