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 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 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 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.
