Spirolox® spiral retaining rings, manufactured exclusively by Smalley, have No Ears To InterfereTM with the mating components in an assembly. Spirals can be interchanged with standard snap ring grooves and offer a 360° retaining surface. Spiral Retaining Rings can be easily assembled and removed without special tools.
Smalley offers 15 different series of Spirolox® spiral retaining rings with over 5,000 rings in stock to select from. Spirals are stocked in both carbon and stainless steel, diameters range from ¼” to 16” (9 mm to 400 mm). Specials can be produced from .200” to 84” (5 mm to 2000 mm).
Spirals are manufactured by coiling the ring from flat wire. This unique process produces a retaining ring that has no protruding lugs or burrs that would interfere in your assembly. The Smalley Ring can be economically produced in carbon steel, stainless steel, coppers, and many other alloys.
TFC offers over 5000 standard spiral rings, which are readily available in both carbon and stainless steel. If you require special designs, take advantage of TFC’s engineers and no-tooling manufacture; a process perfect for large runs, prototypes and midstream design changes. Whatever your application, TFC/Smalley have the cost-effective and innovative design solution.
