Titanium Spring Retainer for 221029D

Titanium Spring Retainer for 221029D

Using Finite Element Analysis, the convoluted O.D. is engineered to provide the optimum balance of fatigue strength, weight and stress distribution.

Holes precisely located through the retainers’ cross section introduce oil to the valve spring at the critical inner to outer spring interface, greatly extending valve spring life.

Finally, the heat-treated aerospace grade titanium alloy is surfaced enhanced with Manley’s exclusive impingement process. This process eliminatesall machining marks, improves fatigue strength and elevates surface hardness, thus reducing wear on both the ID and the spring shelves.
