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高工作循环的耐腐蚀钢制球形滑动轴承的要求特性、检验和试验方法、合格和验收条件。本标准在引用时适用。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。轴承的设计承受低动态径向载荷和在-55°C至120°C（-67°F至248°F）的温度范围内缓慢旋转。衬垫可以是粘合到外环内径的织物或复合材料，或者是在模制成内环和外环之间的预成形空腔的复合材料中。

This European Standard specifies the required characteristics, inspection and test methods, qualification and acceptance conditions for 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. This standard applies whenever referenced. 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 subjected under low dynamic radial loads and slow rotations in the temperature range of −55 °C to 120 °C (−67 °F to 248 °F). The liner may be of a fabric or composite material bonded to the inside diameter of the outer ring or in a composite material moulded into a pre-formed cavity between the inner and outer rings.
