Introduction to Smalley Retaining Rings

As a world-leader and innovator in the retaining ring market, Smalley offers thousands of retaining rings to meet virtually any application requirement. Unlike die-stamped circlips and retaining rings, Smalley retaining rings are coiled on edge from flat wire to the exact diameter required.  They are not stamped. This unique process produces a retaining ring with a uniform cross-section that has no protruding burrs or "Ears to Interfere®" within an assembly. In addition, because coiling produces a retaining ring with no scrap, Smalley rings may be produced quickly and economically.

Smalley offers over 6,000 standard parts which are readily available in both carbon and stainless steel. A wide variety of special alloys and finishes are also available including Inconel, Elgiloy (to NACE® standards), Beryllium Copper, Waspaloy, Hastelloy, Monel, A-286 and others. Special designs are available with deliveries including samples and working prototypes in as little as two weeks with No-Tooling-Costs.  This makes Smalley rings ideal for design work and prototypes, small and large batch runs, and in the case whenever midstream design changes may be required.  Smalley retaining rings meet military and aerospace specifications and are found in thousands of mechanical products around the world.  Whatever your application, Smalley has the cost-effective and innovative design solution.
