本文件规定了带有自调心双列滚珠轴承的可调杆端的特性，其内部径向间隙减小，螺纹杆由耐腐蚀钢制成，设计用于承受负载下的缓慢旋转和振动。 它们包括: -杆端包括: -周向槽以确定位置； -密封或屏蔽； -用于锁定的可选纵向槽； -有球的内环。 这些杆端用于飞行控制杆或航空航天结构杆。 它们的使用温度范围为−54°C至150°C。 但是，使用以下润滑脂进行润滑: -酯型超高压润滑脂（代码A），工作范围−73°C至121°C；或 -超高压润滑脂，合成碳氢化合物，通用（代码B），工作范围−54°C至177°C（见EN 2067）； 当使用代码A润滑脂润滑时，其应用范围限制在121°C。

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.
