The latest revision, , spans 46 pages of highly detailed mechanical instructions, engineering drawings, and quality control metrics. It explicitly covers structural housing constraints, installation tolerances, and the physical deformation parameters required to secure a grooved outer race bearing.
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
Staking utilizes a hydraulic press and stationary anvil dies to apply controlled pressure to a bearing's v-groove, permanently deforming the bearing's material against its housing. The latest revision, , spans 46 pages of
