There are many different types of fasteners on the market, with each type fitting specific applications. While many common fasteners like nuts, bolts, and screws are threaded, there are also unthreaded fasteners that are incredibly versatile in many scenarios and industries. One type of these unthreaded fasteners is retaining rings.
What is a Retaining Ring?
Retaining rings, sometimes called snap clips, are unthreaded fasteners designed to hold parts in place within assemblies. These circular fasteners create a shoulder within a housing/bore or hold components in place on a shaft. Compared to other fasteners that are used in similar applications, retaining rings have a comparably reduced mass which makes them cost-effective for a wide variety of applications in the aerospace, military, automotive, medical, and many other industries. With retaining rings, components are prevented from shifting or loosening during operation, improving overall performance and maintaining alignment.
Types of Retaining Rings
There are various types of retaining rings on the market that are best suited to specific applications, such as tapered and constant snap clips.
- Tapered retaining rings have a tapered design where the ring gets narrower toward the opening. These fasteners have lugs and lug holes, making them easy to remove and install.
- Constant retaining rings have a uniform thickness throughout the component. As a result, these fasteners are good for use in areas with tight clearances, especially in high-speed or high-vibration conditions.
- Spiral retaining rings are shaped like closed circles of uniform thickness that can be wound into grooves. These fasteners are easy to install without tools.
- Bowed and beveled retaining rings are designed to eliminate space between components, allowing for tight joints.
- Radial rings are installed directly into a groove and feature an open-ended design that makes this type of component versatile.
