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
