Spirolox Retaining Rings, also known as Spiral Retaining Rings, are available exclusively from Smalley. Spirolox Retaining Rings have no ears to interfere with mating components in your assembly.


Spirolox Retaining Rings are manufactured by coiling the ring from flat wire. Because coiling produces a retaining ring with no scrap, the Smalley Ring can be economically produced in carbon steel, stainless steel, coppers, and many other alloys. Smalley offers over 6,000 standard rings, which are readily available in both carbon and stainless steel.


If you require special designs, take advantage of Smalley's No-Tooling-Cost process; a process perfect for large runs, prototypes, and midstream design changes. Whatever your application, Smalley has a cost-effective and innovative design solution.
