Unlike a die-stamped circlip/retaining ring, a Spirolox® Retaining Ring (a spiral retaining ring) and a Constant Section Retaining Ring (snap ring) are coiled on edge to the exact diameter required. Spirolox Retaining Rings have a uniform cross-section (or to use our terminology, No Ears to Interfere® within an assembly) and are free of burrs. Spirolox Retaining Rings meet military and aerospace specifications and are found in thousands of mechanical products around the world. Smalley offers spiral retaining rings and snap rings for both internal and external ring applications.
As the leader and innovator in the retaining ring market and inventor of the spiral retaining ring, Smalley offers thousands of retaining rings to meet any application requirements. Smalley retaining rings are available off the shelf in carbon steel, 302 stainless steel, and 316 stainless steel.
Smalley also manufactures Laminar Seal Rings. A Smalley Laminar Seal 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.
Custom retaining ring designs can be manufactured in as little as two weeks. With Smalley's No-Tooling-Cost™ edgewinding manufacturing process, customs, from prototyping to low or high volume requirements, are an affordable alternative if the retaining ring you require is not available. A wide variety of special alloys and finishes are available including Inconel, Elgiloy, A286, Beryllium Copper, and more.
From everyday consumer products like the smartwatch on your wrist to life-saving medical devices such as robotic surgical instruments, retaining rings are trusted all over the world across every industry.
They can be found in extreme environments like oil wells deep under the Earth's surface to as high as the rover on Mars. The only limit retaining rings have is your imagination.
