4、pe - Standardization). It is published for 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
5、interchangeability is affected, physically 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
6、transformation to full European Standard (EN). 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.

After inquiries and votes carried out in accordance with the rules of ASD-STAN defined in ASD-STANs General Process Manual, this standard has received approval for Publ
9、ication. prEN 4266:2010 (E) 3 1 Scope This standard specifies the characteristics of spherical plain bearings, metal to metal, in corrosion resisting steel, cadmium plated and chromated, wide series, inch series for aerospace applications. They are intended for use in fixed or moving parts of the ai
10、rcraft 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-23827C, operating temperature range 73 C to 121 C Code B: Grease as per MIL-PRF-81322G, operating temperat
11、ure 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 surface of the outer or inner ring have to be provided with a dry-film lubricant as per MIL-PRF-46010F or equivalent (anti-seizing protection). The slide
