本标准规定了直径为0和2的耐腐蚀钢刚性单列球轴承的特性，设计用于承受负载下的缓慢旋转和振荡。它们旨在用于飞机结构的固定和移动部件及其控制机构之间，特别是在同一轴线上安装多个轴承，这可能需要减少的间隙和偏差（轴向和径向）

This standard specifies the characteristics of rigid single row ball bearings in corrosion resisting steel of diameter series 0 and 2 designed to withstand only slow rotations and oscillations under load. They are intended for use between fixed and moving parts of the aircraft structure and their control mechanisms, in particular the mounting of more than one bearing on the same shaft axis, which may require reduced clearances and runouts (axial and radial).
