This International Standard specifies the characteristics, boundary dimensions, tolerances, internal clearances and permissible loads of inch series double-row, self-aligning, sealed, heavy duty spherical roller bearings with plain inner rings used in airframe applications. 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.

The airframe roller bearings covered by this International Standard are designed to operate in the temperature range of −54 °C to +150 °C.
