This process uses a hydraulic or mechanical press to apply controlled pressure to a bearing’s v-groove. It is valued for its speed and cost-effectiveness in high-volume production. nas0331 pdf
However, a very common confusion exists in the aerospace fastener community. Many people mistakenly associate all "NAS03xx" series with bolts or screws. While NAS0300 through NAS0320 generally cover shear bolts and tension bolts, NAS0331 often cross-references protective devices. When searching for "nas0331 pdf," you are likely looking for one of two things:
Often considered the gold standard for precision, this method uses a rotary motion—typically a tri-roller swaging tool—to gradually deform the bearing lip. It minimizes axial pressure and reduces the risk of micro-cracks or housing damage. Using the wrong torque on an NAS0331 fastener
