Innovation, quality and engineering excellence has driven Smalley to be the leading manufacturer of Spirolox® Retaining Rings, Constant Section Rings and Wave Springs. We believe that engineers should work with engineers. So our customers work directly with our experienced team. This access to technical expertise and problem solving, prototyping and collaboration is rare in the industry. But it allows you to take your designs further than you thought possible.
Every Smalley ring and spring is backed by our legendary customer support. Our commitment to service combined with our reputation for on-time delivery has earned us an approved supplier status with leading OEM manufacturers around the world. Our commitment is to quality, customer service, and finding the most cost-effective solution.
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.
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.
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.
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.
