Pdf: Nas0331
is the global aerospace industry standard that defines the technical requirements, housing dimensions, and procedural guidelines for the permanent installation and retention of spherical and plain bearings through swaging or staking. Maintained and published by the Aerospace Industries Association (AIA) , this standard ensures that critical bearing assemblies in aircraft control systems, landing gears, and airframe structures remain structurally reliable under severe operational loads, vibrations, and environmental stresses.
Requirements for surface texture, hardness, and protective plating (such as zinc-nickel or cadmium).
