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 rod end comprising: either seals or shields; 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 greases: very high pressure grease, ester type (code A); operational range -73 °C to 121 °C according to MIL-PRF-23827 type II; very high pressure grease, synthetic hydrocarbons, general purpose (code B), operational temperature range -54 °C to 177 °C (see EN 2067), according to MIL-PRF-81322; very high pressure grease, lithium type (code C) operational temperature range -73 °C to 121 °C according to MIL-PRF-23827 type I; when lubricated with codes A and C grease, their field of application is limited to 121 °C. The body responsible for this standard is NA 131-03-03 AA "Teile der mechanischen Systeme" ("Components of mechanical systems") at DIN.
