本欧洲标准规定了在不同操作条件下，具有自润滑衬套、低启动扭矩和低摩擦系数、低振荡下高占空比的耐腐蚀钢制球面滑动轴承的所需特性、检查和试验方法、鉴定和验收条件。 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，尤其是控制机构和操作系统。轴承的设计 在–55°C至120°C（–67°F至248°F）的温度范围内承受低动态径向载荷和缓慢旋转。 衬里可以是粘合到外圈内径的织物或复合材料或 模制在内圈和外圈之间预先形成的空腔中的复合材料。交叉引用: EN 4854-1EN 10204MIL-PRF-87257BTR 4475EN 4854-2ASTM D 1655EN 9133ISO 11078购买时可用的所有当前修订均包含在本文件的购买中。

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.Cross References:EN 4854-1EN 10204MIL-PRF-87257BTR 4475EN 4854-2ASTM D 1655EN 9133ISO 11078All current amendments available at time of purchase are included with the purchase of this document.
