This International Standard specifies the characteristics, boundary dimensions, tolerances, clearances and load
ratings of inch series, single-row, sealed, rigid, intermediate duty, ball bearings with increased precision and
reduced intemal clearance used in airframe applications. These bearings are full complement (without cage) with a
single row of balls and filling slot. These bearings are designed to withstand only slow rotations and oscillations
under load and are intended for use between fixed and moving parts of an aircraft structure and their control
surfaces.
