21、fies the characteristics of spherical plain bearings in corrosion resisting steel, with assembly slots, metric series, with or without lubrication holes and groove, intended for use in fixed or moving parts of aircraft structure and control mechanisms. They may be used in the temperature range from
22、54 C to 150 C. However, as 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
23、 C. Their field of application 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.
