21、parts of aircraft structure and control mechanisms. They may be used in the temperature range from 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 hydrocarb
22、on type very high pressure grease general purpose (code letter B), operating range from 54 C to 177 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 doc
