Smalley has over 6000 Spirolox® Retaining Rings in 302 and 316 stainless steel from stock in 6 mm to 400 mm diameters. Specials can be manufactured from 5 mm to 3000 mm. Smalley’s manufacturing process allows for the economical production of stainless steel retaining rings. Spiral type retaining rings are interchangeable with standard snap ring grooves and have No Ears To Interfere TM with the assembly. Free samples are available of stock parts to test in your application.
Unlike die-stamped circlips / retaining rings, Spirolox® Retaining Rings (Spiral Retaining Rings) and Constant Section Rings 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.
