ANSI/ABMA 14211 (R1999)
This International Standard specifies the characteristics, boundary dimensions, tolerances, clearances and load ratings of inch series, single-row, sealed, rigid, light duty, bail bearings of torque tube design with increased precision and reduced internal 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.
The airframe ball bearings covered by this International Standard are designed to operate in the temperature range of -554 C to 150 C.
Keywords: aircraft industry, rolling bearings, airframe bearings, ball bearings, single-row bearings, precision bearings, specifications, material specifications, characteristics, load capacity, dimensions. overall dimensions, lubrication, designation, marking, imperial system, light duty series.
