EN 2336:20054 1 Scope This standa
19、rd specifies the characteristics of spherical plain bearings in steel, with assembly slots, with or without lubrication holes and grooves, intended for use in fixed or moving parts of aircraft structure and control mechanisms. They may be used in the temperature range from 54 C to 150 C. However, as
20、 they are lubricated with the following greases (see EN 2337): ester type very high pressure grease (code letter A), operating range from 73 C to 121 C or, synthetic hydrocarbon type very high pressure grease general purpose (code letter B), operating range from 54 C to 177 C. Their field of applica
21、tion when lubricated with grease code letter A is limited to 121 C. 2 Normative references The following referenced documents are indispensable for the application of this document.
