Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pa

22、, Uncontrolled Copy, (c) BSI EN 2588:1988 BSI 12-19993 1 Scope This standard specifies the characteristics of spherical plain bearings: without assembly slots with and without grease holes with and without lubrication grooves in corrosion resisting steel intended for fixed and moveable structural el
23、ements in aircraft and their control mechanisms. 2 Field of application The spherical 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
24、A) limits of use 73 to + 121 C or synthetic hydrocarbon extreme pressure grease, for general purpose (code B) limits of use 54 to + 177 C, this field of application in the case of lubrication with grease A is limited to + 121 C. In both cases one of the spherical surfaces shall be smeared with a dry
25、 film lubricant (anti-seize treatment). 3 References ISO 1132:1980, Rolling bearings Tolerances Definitions. EN 2030, Steel FE-PM43 Hardened and tempered Bars D k 150 mm Aerospace series.
