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. NAS0331 The is a Quick Release Pin (often
Staking involves using a hydraulic, mechanical, or pneumatic press to apply high axial force to the bearing's V-groove.
