9、anual, this standard has received approval for Publication. prEN 4156:2010 (E) 3 1 Scope This standard specifies the characteristics of adjustable rod ends with self-aligning double row ball bearing and threaded shank in steel, inner ring and balls in corrosion resisting steel. They consist of : a)

10、a rod end comprising : 1) either seals or shields; 2) an optional longitudinal groove for locking purpose; b) an inner ring with balls. 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.

11、 However, being lubricated with the following greases: a) very high pressure grease, ester type (code A), operational range 73 C to 121 C according MIL-PRF-23827 type II 1) very high pressure grease, synthetic hydrocarbons, general purpose (code B), operational range 54 C to 177 C (see EN 2067), acc

12、ording MIL-PRF-81322. 2) very hight pressure grease, lithium type (code C) operational range 73 C to 121 C according MIL PRF 23827 type I. Their field of application when lubricated with code A grease is limited to 121 C. 2 Normative references The following referenced documents are indispensable fo
