About Smalley:

For over 50 years, Smalley has manufactured retaining rings and wave springs using our unique coiling technology. Smalley has become established as the top manufacturer of spiral retaining rings and flat wire wave springs. Smalley is ISO 9001, ISO/TS 16949, AS9100 and ISO 14001 certified.


Wave/Compression Springs:

Smalley Wave Springs offer the unique advantage of space savings when used to replace coil springs. By reducing spring operating height, wave springs also produce a decrease in the spring cavity. With a smaller assembly size and less material used in the manufacturing process, a cost savings is realized.

Wave springs operate as load bearing devices. They take up play and compensate for dimensional variations within assemblies. A virtually unlimited range of forces can be produced whereby loads build either gradually or abruptly to reach a predetermined working height. This establishes a precise spring rate in which load is proportional to deflection.

Spirolox® Retaining Rings:

Spirolox Retaining Rings, available exclusively from Smalley, have No Ears To Interfere® with the mating components in the assembly. Spiral rings offer a 360° retaining surface, require no special tooling for removal and are interchangeable with ordinary snap ring grooves.

Constant Section Rings:

Constant Section Rings are often specified for heavy duty or impact loading applications. Smalley offers eight series of rings from stock in over 1,000 sizes.

Laminar Sealing Rings:

A Smalley Laminar Sealing Ring is a metallic labyrinth seal consisting of multiple rings in a groove. This arrangement of the rings and the specific orientation of the rings are dictated by the application and the severity of the environment.

Hoopster Rings:

New from Smalley, Hoopster Rings fit into much shallower grooves than regular snap rings or retaining rings. Hoopster Retaining Rings are suitable for light to heavy loads and are ideal for thin wall tubes.

Manufacturing Process:

Smalley offers an exclusive Circular-Grain® Process. This process is not a stamping, but rather a continuous coil that is made from edge-wound, pre-hardened, spring-tempered flat wire. The flat wire has a grain structure that is linear, providing exceptional strength and dimensional stability. Smalley’s unique manufacturing process reduces scrap allowing for the economical production of special alloy products including a large selection of stainless steel retaining rings and wave springs.

No-Tooling-CostTM Process: Smalley’s Circular- Grain® Process offers unusual flexibility in production. There is no special tooling needed, even for prototype or custom configurations. This results in low prototype cost and quick deliveries.

Free Samples: Smalley will send samples of catalog items for your evaluation, free of charge. Simply go to to request free samples, catalogs, download CAD models, design assistance or design your own application specific ring or spring.
