This document specifies the characteristics of adjustable rod ends with self-aligning double row ball bearing with reduced internal radial clearance and threaded shank in corrosion resisting steel, designed to withstand only slow rotations and oscillations under load.

They consist of:

- a rod end comprising:

- circumferential groove to identify location,

- 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, or

- very high pressure grease, synthetic hydrocarbons, general purpose (code B), operational range -54 °C to 177 °C (see EN 2067),

their field of application when lubricated with code A grease is limited to 121 °C.
