19、s. 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-23827C, operating temperature range 73 C to
20、 121 C; Code B: Grease as per MIL-PRF-81322G, 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 surface of the outer or inner ring have to be provided with a dry-film lubricant as per MI
