ABMA 14216:1997(R2008) pdf free.Aerospace – Airframe ball bearings,double-row, self- aligning,sealed, heavy duty – Inch series
This Intermational Standard speifies the characteristics, boundary dimensions, tolerances, intemal clearances and permissible loads of inch series, double-row, self-aligning, sealed, heavy duty ball bearings used in airframe applications. These bearings are fuil complement (without cage) with a double row of balls. These bearings are designed to withstana 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 aiframe ball bearings covered by this Intemational Standard are designed to operate in the temperature range of- 54°C to+ 150 °C.
The following standards contain provisions which, through reference in this text, constitute provisions of this Intemational Standard. At the time of publication, the editions indicated were valid. All standards are subject to revisicn, and parties 0 agreements based on this international Siandaro are encouragea to investigate the possibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid Intermational Standards.

Where cadmium plating is specified (code letters D, M and H), it shall be in accordance with ISO 2082. The external surtaces of bearing rings, except the bore of the inner ring, shall be cadmium plated. Plating on the intemal surfaces shall be at the manutacturers option, except the raceways shall not be plated. The thickness of the plating shall not be less ihan 7 um ana not more than 15 um, except plating on the chamfers of the bore may vary from the specified thickness. The bearing shall be embrittlement-relieved within 4h of plating by heat treatment at 140 °C±10 °C for a minimum of 8 h followed by chromate treatment in accordance with ISO 4520 (code letters D and Honly).
