Swaging utilizes a rotary motion to roll the housing material into the bearing groove. Tools are often used with a drill press or specialized portable equipment.
The specification, formally titled "SCREW, MACHINE - PAN HEAD, CROSS RECESS, FILLISTER HEAD, DRILLED, 100 DEGREE COUNTERSUNK HEAD, CORROSION AND HEAT RESISTANT STEEL, UNJF THREAD" (note: always verify the exact title with the latest AIA/NAS release), defines a specific family of precision fasteners used in extreme environments. nas0331 pdf
: Standardized around aerospace-grade hardware like the MS14101 (narrow series) and MS14103 (wide series) spherical bearings. Critical Methods Detailed in the Standard
NAS0331 is a quality management system (QMS) standard specifically designed for the aerospace industry. It provides requirements for organizations to establish, implement, maintain, and continually improve a QMS that meets the needs of the aerospace industry.
are often used for bearing installation and meet requirements for key specifications like NAS0331 Method 200. The specification, formally titled "SCREW, MACHINE - PAN
Compliance with NAS0331 and related MIL-SPEC standards ensures that every bearing is traceable, certifiable, and proven to be airworthy, providing the foundation for MRO (Maintenance, Repair, and Overhaul) quality assurance.
Unlike fastener-focused NAS standards (like NAS1330), NAS0331 is a process specification, defining how to perform a critical assembly task. Understanding this distinction is key: you would use a fastener standard (e.g., NAS1330) to the correct part for a job, but you would turn to NAS0331 to correctly and safely install a bearing.
For MRO operations, especially those supporting aging aircraft, the portable swaging tools that meet NAS0331 Method 200 are invaluable. Their ability to perform on-wing bearing repairs in tight spaces minimizes downtime and prevents unnecessary removal of major assemblies. NAS0331 provides a consistent, auditable process for installers, ensuring that repairs are done correctly the first time. auditable process for installers
