Understanding the NAS0331 Standard: Bearing Installation and Retention It ensures structural integrity for spherical bearings in
As a National Aerospace Standard (NAS), NAS0331 is a proprietary document subject to copyright and must be obtained from authorized distributors.
NAS0331 is an Aerospace Industries Association (AIA) standard defining procedures for bearing installation and retention through swaging or staking. It ensures structural integrity for spherical bearings in housings, utilizing specific methods (Method 100/200, 400) to meet, flight-critical, FAA and EASA audit requirements.

The standard incorporates precise and specifies that the bore diameters and tolerances of the housing must comply with Requirement 202 of MIL-STD-1599 . MIL-STD-1599 is a military standard that specifies all required methods for using bearings, control system components, and associated hardware in the design and construction of aerospace mechanical systems. By referencing MIL-STD-1599, NAS0331 ensures that the housing is prepared to an exacting military standard for aerospace use.
