The "NAS" designation indicates that this part meets the rigorous quality and dimensional standards required for flight-critical aerospace applications.

If that's the case, here is some general information:

The NAS0331 engineering standard outlines how to properly install and retain a bearing using plastic deformation techniques. In aerospace applications, bearings cannot simply be pressed into a housing; extreme vibrations, thermal cycling, and high axial loads require positive mechanical retention to prevent displacement.

Tooling manufacturers have designed specific product lines to conform to NAS0331. For example, the AST3016 Portable Tri-Roller Swager is explicitly designed to meet NAS0331 Method 200 specifications alongside other aerospace standards like BAC5435 and BPS4162. Similarly, staking tools must conform to the geometric and material specifications outlined in the standard to ensure the anvil dies do not crack or mar the bearing surface during installation.

NAS0331 addresses this by outlining how to displace the metal of either the bearing's V-groove or the housing itself to form a permanent mechanical lock. The standard applies to any structural housing material (such as aluminum, titanium, or steel alloys) and focuses predominantly on standard Military Specification (Mil-Spec) Corrosion Resistant Steel (CRES) race bearings.

Requirements for balls and outer rings made from specific alloys (e.g., 440C or PH13-8Mo ). The technical specifications in the govern: NAS0331 Bearing

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.

The most direct and reliable source for datasheets is usually the official website of the component's manufacturer. Companies often maintain comprehensive databases of their products, including obsolete or older parts.
