After e
16、nquiries and votes carried out in accordance with the rules of this Association, this Standard 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 na
17、tional standard, either by publication of an identical text or by endorsement, at the latest by December 2006, and conflicting national standards shall be withdrawn at the latest by December 2006. Attention is drawn to the possibility that some of the elements of this document may be the subject of
18、patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights.

EN 4041:20064 1 Scope This standard specif
20、ies the characteristics of rigid single row ball bearings in corrosion resisting steel with an extended inner ring and a solid or lightweight flanged alignment bush, designed to withstand only slow rotations and slight oscillations under load. They are intended for use in airframe fixed and moving e
21、lements and in flight control linkages. The bearings defined in this standard shall be used in the temperature range from 54 C to 150 C. However, as they are lubricated with the following greases (see EN 3727): ester type very high pressure grease (code letter A), operating range from 73 C to 121 C
22、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 letter A grease is limited to 121 C. 2 Normative references The following referenced documents are indispensable for the
