Post-installation plating requirements, such as zinc-nickel or cadmium.
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.

This is the most direct method, using a hydraulic or mechanical press with a stationary anvil die. The die applies controlled pressure to the bearing's v-groove, deforming the housing material to secure the bearing. It is valued for its speed and cost-effectiveness, making it ideal for high-volume production of non-critical components. However, the high pressure required can risk deforming the bearing's outer ring.
