3、, mit Gelenklager nach EN4265 aus korrosionsbestndigem Stahl mit Innengewinde Mae und Belastungen Inch Reihe This “Aerospace Series“ Prestandard has been drawn up under the responsibility of ASD-STAN (The AeroSpace and Defence Industries Association of Europe - Standardization). 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. Edition approved for publication 31 October 2007 Comments should be sent within six months after the date

11、readed shank. They are intended for use in fixed or moving 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 ran
12、ge 73 C to 121 C, Code B: Grease as per MIL-PRF-81322, operating 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
13、 as per MIL-PRF-46010 or equivalent (anti-seizing protection). 2 Normative references The following referenced documents are indispensable for the application of this document.
