They consist of: a rod end comprising: circumferential groove to identify location; either seals or shield

22、s; an optional longitudinal groove for locking purpose; an inner ring with balls. 2 Field of application These rod ends are intended for use with flight control rods or rods for aerospace structures. They are intended to be used in the temperature range:54 C to+150 C. However, being lubricated with

23、the following greases(seeEN2067): Extreme pressure grease, type ester (code A), operating range73 C to+121 C Extreme pressure grease, type synthetic hydrocarbon general usage (code B), operating range54 C to+177 C their field of application in the code A is limited to+121 C. 3 Normative references I
