Characteristics
Retaining Rings
Unlike die-stamped circlips / retaining rings, Spirolox Retaining Rings and Constant Section Rings are coiled on edge to the exact diameter required.
They 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.
Manufacturing
Edgewinding, also known as "The No-Tooling-Cost Process", is our precision forming operation that coils pre-tempered flat wire on edge to create a near-perfect circle. Circular-Grain metallurgy gives our products strength and stability far superior to that of conventional retaining rings and wave washers which are simply stamped through the metal grain.
Edgewound products can be coiled to your exact specification in any diameter and with any number of turns (layers or coils), effectively eliminating material waste. As flexible as it is precise, our edgewinding process accommodates your design changes without the need for additional tooling and die modifications. This facilitates your developmental work, allowing us to produce your low-quantity custom orders and your working prototypes quickly and economically. Even after your initial prototype is produced, or in mid-stream production, our edgewinding process allows us to alter your design or dimensions with simple machine adjustments or a change in raw material size. After the revised specifications are approved, we complete and document the final setup. Then, we quickly resume production of your order, whether it consists of one part or one million.
Prototypes
About the easiest way to test a theoretical design is to produce a working prototype a task at which excels. A prime example is the development of a custom wave spring. We can adjust dimensions, by changing the number of waves and the number of turns, and trying different combinations of spring variables. Finally, we test for function, before production, so we know we have it right. We produced prototypes are also the most economical way to provide results on a trial-and-error basis. From one to a thousand pieces, we can produce, try, modify, and reproduce your design as often as necessary - all without special tooling costs.
Advantages of Spirolox® Retaining Rings
Spirolox Retaining Rings have No Ears to Interfere in your assembly! Spirolox Rings are manufactured by coiling the ring from flat wire. This unique process produces a retaining ring that has no protruding ears or burrs to interfere with your assembly. Because coiling produces a retaining ring with no scrap, the Spirolox Ring can be economically produced in carbon steel, stainless steel, coppers, and many other alloys.
Gandini offers over 6,000 standard parts, which are readily available in both carbon and stainless steel. If you require special designs, take advantage of gandini's No-Tooling-Cost process; a process perfect for large runs, prototypes and midstream design changes. Whatever your application, Gandini has the cost-effective and innovative design solution.
- 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-Charge on special designs
- Easy installation and removal
