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 standard incorporates precise and specifies that the bore diameters and tolerances of the housing must comply with Requirement 202 of MIL-STD-1599 . MIL-STD-1599 is a military standard that specifies all required methods for using bearings, control system components, and associated hardware in the design and construction of aerospace mechanical systems. By referencing MIL-STD-1599, NAS0331 ensures that the housing is prepared to an exacting military standard for aerospace use.
For any mathematical equations I will make sure to use $$ syntax without newlines for example $$x+5=10$$. nas0331 pdf
Staking involves using a hydraulic, mechanical, or pneumatic press to apply high axial force to the bearing's V-groove.
