BS EN 4265:2013EN 4265:2013 (E) 4 1 Scope This European Standard specifies the characteristics of spherical plain bearings, metal to metal, in corrosion resisting steel, passivated, wide series, inch series for aerospace applications. They are intended for use in fixed or moving par

18、ts 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-23827C, operating temperature range 73 C to 121 C. Code B: Grease as per MIL-PRF-81322G, opera

19、ting 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 surface of the outer or inner ring have to be provided with a dry-film lubricant as per MIL-PRF-46010G or equivalent (anti-seizing protection

20、).
