15、2588:20063 Foreword This European Standard (EN 2588:2006) has been prepared by the European Association of Aerospace Manufacturers - Standardization (AECMA-STAN). After enquiries and votes carried out in accordance with the rules of this Association, this Standard has received the approval of the Na

16、tional Associations and the Official Services of the member countries of AECMA, prior to its presentation to CEN. 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 November 2006, and conflicting nat

17、ional standards shall be withdrawn at the latest by November 2006. 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. This European Stand

18、ard supersedes EN 2588:1988. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Icelan

EN 2588:20064 1 Scope This standard specifies the characteristics of spherical plain bearings in corrosion resisting steel,

20、with assembly slots, metric series, with or without lubrication holes and groove, intended for use in fixed or moving parts of aircraft structure and control mechanisms. They may be used in the temperature range from 54 C to 150 C. However, as they are lubricated with the following greases (see EN 2

21、337): ester type very high pressure grease (code letter A), operating range from 73 C to 121 C or, synthetic hydrocarbon 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 grease code letter A is limited

22、 to 121 C. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.
