17、. BS EN 4156:2013EN 4156:2013 (E) 4 1 Scope This European 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 rod end comprising: either seals or sh
18、ields; an optional longitudinal groove for locking purpose; 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. However, being lubricated with the following grea
19、ses: very high pressure grease, ester type (code A), operational range 73 C to 121 C according MIL-PRF-23827 type II very high pressure grease, synthetic hydrocarbons, general purpose (code B), operational range 54 C to 177 C (see EN 2067), according MIL-PRF-81322. very high pressure grease, lithium
20、 type (code C) operational range 73 C to 121 C according MIL-PRF-23827 type I. Their field of application when lubricated with codes A and C grease is limited to 121 C. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensa
