After enquiries and votes carried out in accordance with the rules of this Association, this Standa

16、rd has received the approval of the National 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

17、 by November 2006, and conflicting national standards shall be withdrawn at the latest by November 2006.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 s

EN 4036:20064 1 Scope This standard specifies the characteristics of adjustable rod ends with self-aligning double row ball bearing wi

20、th reduced internal radial clearance and threaded shank in corrosion resisting steel, designed to withstand only slow rotations and oscillations under load. They consist of: a rod end comprising: circumferential groove to identify location; either seals or shields; an optional longitudinal groove fo

21、r locking purpose; an inner ring with balls. These rod ends are intended for use with flight control rods or rods for aerospace structures. They are intended to be used in the temperature range: 54 C to 150 C. However, being lubricated with the following greases: very high pressure grease, ester typ

22、e (code A), operational range 73 C to 121 C or very high pressure grease, synthetic hydrocarbons, general purpose (code B), operational range 54 C to 177 C (see EN 2067), their field of application when lubricated with code A grease is limited to 121 C. 2 Normative references The following reference
