Tapered Section Retaining Rings (Circlips)

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

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 can be used to simplify installation and removal
• Available in Spring Steel SAE 1060 and 1074

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. 

• Internal Circlip Installation

• External Circlip Installation

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.
