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