Precise measurements of the movement between the ball and the outer ring after installation. No-Load Torque:
Properly installed bearings resist axial loads and prevent loosening under high-vibration aerospace environments.
NAS0331 (National Aerospace Standard 0331) establishes critical industry requirements for the installation and retention of aerospace bearings using swaging and staking techniques, focusing on material compatibility and load capacity. The standard defines precise specifications for housing tolerances, no-load torque values, and inspection criteria to ensure structural integrity.

The document provides the technical requirements for the installation process to ensure flight safety and mechanical reliability. Key features include:
is the global aerospace industry standard that defines the technical requirements, housing dimensions, and procedural guidelines for the permanent installation and retention of spherical and plain bearings through swaging or staking. Maintained and published by the Aerospace Industries Association (AIA) , this standard ensures that critical bearing assemblies in aircraft control systems, landing gears, and airframe structures remain structurally reliable under severe operational loads, vibrations, and environmental stresses. Precise measurements of the movement between the ball
The NAS0331 standard serves as a foundational document for aerospace maintenance and manufacturing, defining how bearings should be permanently installed into housings. In high-stress aviation environments, simply pressing a bearing into place is insufficient; it must be "retained" using specific mechanical methods like to prevent movement under extreme vibration and load. AeroStaking 2. Core Retention Methods
The is a Quick Release Pin (often referred to as a "Ball Lock Pin"). These pins are used for rapid assembly and disassembly of components. They feature a solid shaft with a locking mechanism (usually steel balls) at one end and a release mechanism (a push-button or ring) at the other.
(National Aerospace Standard) is a technical specification for heavy-duty, high-strength structural blind rivets
is the definitive global aerospace standard governing the installation, retention, and testing of spherical bearings used in critical structural housings. Formally titled "Bearing Installation and Retention by Swaging or Staking," this specification is managed by the Aerospace Industries Association (AIA). It provides strict guidelines that commercial and military aviation Maintenance, Repair, and Overhaul (MRO) facilities, as well as original equipment manufacturers (OEMs), must follow to ensure safety and structural integrity. Engineers and technicians frequently search for the NAS0331 PDF to access exact tolerances, mechanical methods, and proof-testing protocols. : A typical includes data sheets and technical
