Staking involves using a hydraulic, mechanical, or pneumatic press to apply high axial force to the bearing's V-groove.

Understanding AIA/NAS NAS0331: The Definitive Guide to Aerospace Bearing Installation, Swaging, and Staking

: Ensures that the internal radial play and no-load torque values of the bearing have not been compressed or compromised by excessive installation forces. nas0331 pdf

The , titled Bearing Installation and Retention by Swaging or Staking , is a critical regulatory document managed by the Aerospace Industries Association (AIA) that defines the universal procedures for securing grooved outer-race bearings into aerospace structural housings. Sourcing an authorized NAS0331 PDF ensures compliance for Maintenance, Repair, and Overhaul (MRO) facilities and aerospace manufacturers requiring precise, flight-certified mechanical retention. 🛠️ What is the NAS0331 Standard?

: The assembly is placed into a specialized Proof Load Test Machine . An axial static force is ramped up at a controlled rate (typically 1% per second) to verify that the swaged lip can withstand specified shear forces without shifting.

:

Post-installation plating requirements, such as zinc-nickel or cadmium.

While this specialized tooling is essential, the aerospace industry does not operate in isolation. Many complementary standards and regulations work in concert with NAS0331 to create a complete framework for bearing safety and reliability. It's worth briefly examining how NAS0331 fits into the larger ecosystem of regulatory standards. : Includes sampling plans and procedures for inspection

The current version of this standard is the , published on July 31, 2020 . Core Installation Methods

Originally published in June 1992, the document has gone through key revisions to keep pace with changing metallurgy and precision tooling, with Revision 2 representing the active baseline for current operations. Official, secure PDF versions are strictly controlled and distributed by authorized technical hubs such as the Accuris Standards Store . Core Methodologies: Staking vs. Swaging
