This International Standard specifies the characteristics, boundary dimensions, tolerances, internal clearances and permissible loads of metric series double-row, self-aligning ball bearings of diameter series 2, in accordance with ISO 15, used in airframe applications. These bearings are full complement (without cage) with a double row of balls. 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 ball bearings covered by this International Standard are designed to operate in the temperature range of − 54 °C to + 150 °C.
