No Gap - 360° retaining surface
No protruding ears to interfere with mating components (uniform cross-section)
Economically produced in stainless steel because the coiling process produces no scrap
No-Tooling-Charges™ on custom designs
Easy to assemble and remove
No gap or lugs provide for a functional and aesthetically pleasing ring
Can operate in an internal and external groove at the same time
Spirolox Retaining Rings, also known as Spiral Retaining Rings, are available exclusively from Smalley.
Spirals have no ears to interfere with mating components in your assembly. Spirals 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 custom 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 the cost-effective and innovative design solution.
Interchangeable Grooves
Spiral retaining rings are interchangeable with ordinary snap ring (Circlip) grooves. Find the right ring for your application by visiting our Interchange Listing page.
The EH & ES Series metric retaining rings are Smalley's standard Spiral Retaining Rings produced to Metric Aerospace specifications. They fit grooves specifically designed for 2-turn spiral retaining rings and accommodate light to medium duty applications.
