本欧洲标准规定了具有自润滑衬套、低起动转矩和低摩擦系数、在不同运行条件下低振动下的高占空比、航天应用广泛系列的耐腐蚀钢制球面滑动轴承的特性。这些自润滑球面滑动轴承用于飞机结构的固定或移动部件，特别是控制机构和操作系统。轴承设计用于承受低动态径向负载和在-55°C至120°C（-67°F至248°F）的温度范围内缓慢旋转。

This European Standard specifies the characteristics of spherical plain bearings in corrosion resisting steel with self-lubricating liner, low starting torque and low friction coefficient, elevated duty cycles under low oscillations at different operating conditions, wide series for aerospace applications. These self-lubricating spherical plain bearings are intended for use in fixed or moving parts of the aircraft structure especially for control mechanism and operating systems. The bearings are designed to be subjected under low dynamic radial loads and slow rotations in the temperature range of −55°C to 120 °C (−67 °F to 248 °F).
