Titanium Pin Retention Systems: Clevis, Cotter, Spring and Retaining Rings
2026-08-11
A reliable titanium retention system begins with joint function: pivot, secondary locking, interference-fit location or axial groove retention. The correct product depends on the complete assembly and service conditions.
Product-to-Function Map
| Product | Typical function | Key definition |
|---|---|---|
| Clevis pin | Removable pivot or linkage | Shank fit, usable length, head and cross-hole |
| Cotter pin | Secondary retention through a cross-hole | Wire, length, eye, prongs and installed clearance |
| Spring pin | Interference-fit location or retention | Free pin geometry, mating hole and force |
| Retaining ring | Axial retention in shaft or bore groove | Ring section, groove, installation strain and load |
Application Review
Marine and chemical equipment require review of crevices, deposits, dissimilar-metal contact and maintenance. Aerospace and other lightweight mechanisms add fatigue, vibration, traceability and qualification requirements. In every case, titanium grade alone does not validate the finished joint.
