The standard, officially titled " Bearing Installation and Retention by Swaging or Staking ," is a critical technical document for the aerospace industry. Developed by the Aerospace Industries Association (AIA) , this standard establishes the mandatory requirements for installing bearings into structural housings and ensuring they remain securely in place under high-stress flight conditions.

It is the primary industry guideline for how aerospace bearings—specifically spherical and plain bearings—are permanently secured into their housings. 🔩 Primary Features of NAS0331 nas0331 pdf

The NAS0331 standard serves as a foundational document for aerospace maintenance and manufacturing, defining how bearings should be permanently installed into housings. In high-stress aviation environments, simply pressing a bearing into place is insufficient; it must be "retained" using specific mechanical methods like to prevent movement under extreme vibration and load.
