Insert, Screw Thread, Helical Coil Metric Series, Standard Assembly Dimensions for

2019-07-01
CURRENT
MA1567C
This SAE Metric Aerospace Standard (MA) provides for helical coil screw thread inserts, both free running and self-locking, installation screw thread dimensional data and guidance on insert length selection. The document also provides formulas for determining requirements when non standard insert lengths are necessary.

Groove Design - Metal Face Seal

2019-06-06
CURRENT
AIR1108A
Groove designs presented herein are applicable for use with machined or formed metal seals which are similar in configuration to those shown in figure 3, which operate under internal pressure or in vacuum service and which have been specifically qualified or recommended by the purchaser or the manufacturer for use with this AIR. They are also applicable for use with metal o-rings (e.g., MS9142, MS202 thru MS9205) where interchangeability with machined or formed metal seals is desired. For metal o-ring groove designs where inter-changeability is not a requirement refer to ARP 674.

Bolts, Screws, and Studs, Geometric Control Requirements

2019-02-26
CURRENT
AS3063C
This SAE Aerospace Standard (AS) establishes the geometric control requirements for bolts, screws, and studs where worded notes and symbolized notes are used for straightness, concentricity, squareness, and runout.

Screw Threads, Metric Buttress - MJB Profile

2019-01-03
CURRENT
MA1696B
This standard establishes the basic triangular profile for the MJB thread form, the design profiles, standard pitches, tolerance classes, formulae for tolerances and dimensions, tolerance tables, and a system of designations. Because of the specialized application for buttress threads, no preferred diameter-pitch series have been established for this standard and each application will require use of the thread formulae for dimensions and related tolerances given herein for deriving the thread dimensional requirements.

CURRENT
AIR18B
This SAE Aerospace Information Report (AIR) records the results of an investigation of a dual rotation propeller shaft standard for an engine supplied bearing and the reason for deciding that such a bearing is impracticable.

Modules and Basic Racks of Metric Spur and Helical Gears

2018-09-11
CURRENT
AS1560B
This SAE Aerospace Standard (AS) establishes the standard modules for aerospace metric involute gear teeth and establishes the tooth dimensions of aerospace metric involute gear teeth in terms of the conjugate rack type cutter whose counterpart reference profile is called the basic rack profile of the generated gear, having the tooth dimensions expressed in terms proportional to the module.
