22、al plain bearings: without assembly slot with and without swaging grooves with and without grease holes with and without lubrication grooves in corrosion resisting steel intended for fixed and moveable structural elements in aircraft and their control mechanisms. 2 Field of application The spherical
23、 plain bearings defined by this standard are to be used within the temperature range 54 to + 150 C. However, because of lubrication with the following greases (see EN 2337): ester type extreme pressure grease (code A) limits of use 73 to + 121 C or synthetic hydrocarbon extreme pressure grease, for
24、general purpose (code B) limits of use 54 to + 177 C, the field of application in the case of lubrication with grease A is limited to 121 C. In both cases the spherical surface of the outer ring shall be smeared with a dry film lubricant (anti-seize treatment). 3 References ISO 1132:1980, Rolling be
