8、sh Standard has been prepared under the direction of the Aerospace Standards Policy Committee and is the English language version of EN 2336 “Aerospace series. Bearings spherical plain in steel with assembly slots. Dimensions and loads” published by the European Committee for Standardization (CEN).
9、EN 2336 was produced as a result of international discussion in which the UK took an active part. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard do
10、es not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, the EN title page, pages 2 to 8, an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had amendme

21、bearings: with assembly slots with and without grease holes with and without lubrication grooves in steel intended for fixed and moveable structural elements in aircraft and their control mechanisms. 2 Field of application The spherical plain bearings defined by this standard are to be used within t
22、he 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 general purpose (code B) limits of use 54 to + 177 C, their fiel
23、d 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 film lubricant (anti-seize treatment). 3 References ISO 1132:1980, Rolling bearings Tolerances Definitions.
