Smalley engineers have worked on over 25,000 applications. Whether it’s a prototype or production run, we are quickly and easily able to make modifications during any stage of the process, so custom rings get delivered fast and with No-Tooling-Costs ™. When stamping a custom ring, additional tooling costs are necessary to cover any new punches and dies, often with long lead times. Because no material waste is produced during edgewinding, custom materials become more economical.Īnother benefit of our edgewinding, No-Tooling-Cost process is design flexibility. Stamping a ring produces excess scrap from the center, which is especially important for expensive materials and large diameters. What this means for you is quickly and economically manufactured rings. Smalley’s edgewinding process works by taking flat wire and coiling it on edge. Snap rings are traditionally stamped out of sheet metal, as seen in the image below. Smalley Spirolox retaining rings are made by edgewinding, the only manufacturing process we trust to deliver precise yet flexible solutions. Now that you know what a retaining ring is and why it’s used, we’ll go over how a retaining ring is made. Spirolox rings can be installed by spiraling the ring into the groove and have a removal notch for simple removal with no special tools.įor a more detailed explanation of the advantages of using a Spirolox retaining ring, read our Retaining Ring vs. Lastly, they are easy to install and remove in comparison to other rings, which require snap ring pliers. They also have no gap, so they provide a 360 ° retaining surface for even load distribution while securely holding the mating component in place. They have a uniform cross-section and are more aesthetically pleasing. Since Spirolox rings have No-Ears-to-Interfere ®, they will smoothly integrate with mating components with a low radial profile. Traditional snap rings have ears, or so-called lugs. While there are other types of rings available, engineers specify Spirolox retaining rings because of their low radial profile, reliability, and convenience.Īn advantage of using a Spirolox retaining ring, also known as a spiral retaining ring, in your application is its unique configuration. Why would you use a Spirolox Retaining Ring over other rings? Two dozen were replaced by two Spirolox retaining rings in the gearbox assembly pictured below. A single retaining ring can replace multiple bolts on a gear assembly, eliminating the need for drill and tapping holes while also simplifying the installation process, and therefore time. Used as an alternative to machining a shoulder, retaining rings eliminate complex machining processes, ultimately saving time, weight, and production cost for a more efficient production process.Ī retaining ring can also streamline your assembly. Internal External Why would you use a retaining ring?Ī retaining ring functions as a removable shoulder. As the name suggests, an internal ring sits in a housing groove, whereas an external ring sits in a shaft groove. You can have an internal (housing) retaining ring or an external (shaft) retaining ring. So what is a retaining ring and when should I use it? What is a retaining ring?Ī retaining ring is a type of industrial fastener that holds mating components or assemblies together.Ī retaining ring is a circular component made out of metal that sits in a groove (housing or shaft). Here at Smalley, we manufacture retaining rings. So if we have many different types of fasteners, how do I know which one to use?įiguring out which fastener to use goes back to the application.įactors like the environment it’s exposed to, ease of installation, material or weight limitations, cost, aesthetics, and reusability should all be taken into consideration. When you staple a piece of paper or hang a painting on a wall, you’re joining two things together through the means of a fastener. Nails, screws, nuts, bolts, pins- the list goes on.
