Rationale
AS81935/4 IS BEING REVISED TO CLARIFY THE KEYWAY PART NUMBER ORDERING INFORMATION. CLARIFIED THE PART NUMBER ORDERING OPTIONS FOR THE -03AK. THE KEYWAY FLAT DIMENSIONS WERE CLARIFIED ON THE -03AK. THE -03A PART NUMBER WAS CANCELLED AND SUPERSEDED BY -03B. THE -03B IS A PART NUMBER CHANGE ONLY, DIMENSIONALLY IDENTICAL TO -03A. THE -03B WAS CREATED TO SOLVE THE PROBLEM CREATED WHEN THE AS81820 “A” SUFFIX LINER WAS USED ON THE -03.

KEYWAY SHALL BE ORIENTED ALONG THE CENTERLINE OF THE THREADED SHANK. THE PLANE OF THE BOTTOM OF THE KEYWAY SHALL BE PARALLEL TO THE PLANE MADE BY THE FACE OF THE ROD END HOOP.

KEYWAY, WHEN SPECIFIED, IS COMPATIBLE WITH LOCKING DEVICES: AS81935/3 FOR SIZES –03 THROUGH –08, AND NAS 513 FOR SIZES –10 THROUGH –16. KEYWAY TOLERANCES NOT SPECIFIED SHALL BE IN ACCORDANCE WITH AS81935/3 OR NAS 513 AS APPLICABLE.

(c)
THREADS SHALL BE FORMED BY A SINGLE ROLLING OPERATION AFTER FINAL HEAT TREAT AS SPECIFIED IN THE THREAD SECTION OF AS81935.

(d)
THE -03A WAS CANCELLED AND SUPERSEDED BY -03B. THE -03A WAS CREATED BEFORE THE ADDITION OF THE AS81820 TYPE A LINER OPTION. A PART NUMBER CONFLICT EXISTED IF THE -03 WAS ORDERED WITH THE “A” AS81820 OPTION PTFE LINER. THE CONFLICT EXISTED BECAUSE THE -03A DASH NUMBER COULD ONLY BE ORDERED WITH THE KEYWAY OPTION. THE -03A WAS CREATED TO LIMIT THE KEYWAY BREAKOUT SO IT DID NOT ENTER THE ROD END BODY I.D. CHAMFER. THE -03A OPTION COULD ONLY BE ORDERED WITH THE KEYWAY OPTION CONTAINING A “K” IN THE PART NUMBER SUFFIX. IN ORDER TO OVERCOME THE AS81820 TYPE “A” LINER CONFLICT, THE -03A WAS CANCELLED, SUPERSEDED, AND REPLACED BY THE -03B.

Issuing Committee
The objective of the Airframe Control Bearing Group (ACBG)is to provide industry experience and state of the art technology for airframe bearings, and issue as appropriate, published documents known as SAE Aerospace Standards. The focus of the Committees is present and future aircraft airframe control systems, bearings, and associated components.
The ACBG shall be responsible for the preparation, development, maintenance and promotion of all relevant specifications, standards, and requirements for airframe bearings, control system components, and associated hardware used in the design and construction of aerospace mechanical systems and subsystems. The ACBG shall also coordinate with other organizations for lubricants, control cables, and locking devices and shall utilize and promote the use of specifications published by those organizations. The ACBG shall function as a forum for technology transfer as it affects the Airframe bearing and control systems industry and for the enhancement of distribution channels.Reference
* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
