It is published for
4、the needs of the European Aerospace Industry. It has been technically approved by the experts of the concerned Domain following member comments. Subsequent to the publication of this Prestandard, the technical content shall not be changed to an extent that interchangeability is affected, physically
5、or functionally, without re-identification of the standard. After examination and review by users and formal agreement of ASD-STAN, it will be submitted as a draft European Standard (prEN) to CEN (European Committee for Standardization) for formal vote and transformation to full European Standard (E
6、N). The CEN national members have then to implement the EN at national level by giving the EN the status of a national standard and by withdrawing any national standards conflicting with the EN.

9、 Publication. prEN 6057:20073 1 Scope This standard specifies the characteristics of adjustable rod-ends consisting of: a spherical plain bearing, metal to metal, in corrosion resisting steel, wide series (EN 4265), a rod-end with internal threaded shank. They are intended for use in fixed or moving
10、 parts of the aircraft structure and their control mechanisms. They shall be used in the temperature range 54 C to 150 C. As they are lubricated by means of the following greases: Code A: Grease as per MIL-PRF-23827, operating temperature range 73 C to 121 C, Code B: Grease as per MIL-PRF-81322, ope
11、rating temperature range 54 C to 177 C. The range of application for bearings lubricated with grease per code A is limited to 121 C. In both cases the spherical surfaces of the outer or inner ring have to be provided with a dry-film lubricant as per MIL-PRF-46010 or equivalent (anti-seizing protecti
12、on). 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.
