Tapered Section Retaining Rings (Circlips)
With over 100 years of manufacturing excellence, Smalley is the Engineer's Choice® for supplying or designing the right retaining ring solution for all of your application needs.
Smalley has recently partnered with Beneri, the leading Italian circlip manufacturer since 1958, to bring you even more retaining ring solutions at the same quality you trust.
We now offer Tapered Section Retaining Rings (Circlips) from stock in addition to Spirolox and Constant Section Snap Rings.
*These products are only available for sale for United States-based customers
What is a Tapered Section Retaining Ring (Circlip)?
Tapered section retaining rings, also referred to as circlips, are retaining rings with a tapered radial wall. They are designed for high thrust loads and heavy-duty applications.
Tapered section retaining rings can be axially installed into a bore/shaft groove to safely secure assemblies in place. The tapered radial width decreases from the top to the free ends, ensuring nearly full contact with the groove when installed.
Advantages of Tapered Section Retaining Ring (Circlips)
- Can withstand significant thrust loading
- Tight tolerances to industry standards and specifications
- Circlip pliers may be used to simplify installation and removal
- Available in Spring Steel SAE 1060 and 1074
Tapered Section Retaining Ring Applications
Beneri circlips are trusted all over the world in various applications such as:
- Automotive and Agricultural Machinery (Engines, Transmission Components, Suspensions, Breaks)
- High-Temperature Machinery
- Naval Industry
- Furniture Industry
- And much more!

Internal Tapered Section Retaining Rings
RSHE (Imperial) and RSHD (Metric)
Axially assembled retaining rings for bores, designed to be installed into a housing groove.
The ring functions as a removable shoulder, safely securing the assembly.
External Tapered Section Retaining Rings
RSSE (Imperial) and RSSD (Metric)
Axially assembled retaining rings for shafts, designed to be installed into a shaft groove.
The ring functions as a removable shoulder, safely securing the assembly.

Installation and Removal
Tapered section retaining rings (circlips) have lugs and lug holes that aid in installation and removal via retaining ring pliers. Ring expansion and contraction should be limited to avoid possible deformation caused by installation. See our Installation and Removal Guides below for more information.
FOR DIN-471
We recommend using pliers DIN 5254, which have stop and return screws to safely and gradually control ring expansion.
FOR DIN-472
We recommend using pliers DIN 5256, which have stop and return screws to safely and gradually control ring contraction.
