is the definitive global aerospace standard governing the installation, retention, and testing of spherical bearings used in critical structural housings. Formally titled "Bearing Installation and Retention by Swaging or Staking," this specification is managed by the Aerospace Industries Association (AIA). It provides strict guidelines that commercial and military aviation Maintenance, Repair, and Overhaul (MRO) facilities, as well as original equipment manufacturers (OEMs), must follow to ensure safety and structural integrity. Engineers and technicians frequently search for the NAS0331 PDF to access exact tolerances, mechanical methods, and proof-testing protocols. nas0331 pdf

Swaging employs a rotary motion, typically via a drill press or specialized tri-roller tool, to gradually roll the bearing's v-groove into place, forming a secure fit. Portable versions of these tools allow for on-site repairs and are often used for on-wing bearing retention and replacement in constrained spaces.

Utilizes a rotary motion—often with a Tri-roller tool —to deform the bearing's V-groove into the housing. This is preferred for high-precision applications requiring low axial pressure. It typically spans approximately 46 pages
