ISO 14207 pdf download.Aerospace — Airframe ball bearings, single-row, rigid, precision, sealed, light duty — Inch series 1 Scope This International Standard specifies the characteristics, boundary dimensions, tolerances, internal clearances and permissible loads of inch series, single-row, sealed, rigid, light duty, ball bearings with increased precision and reduced clearances 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 – 54 °C to + 1 50 °C. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.
