A circlip, also known as a retaining ring or snap ring, is a versatile fastener composed of a partially flexible ring with open ends. This ring restricts lateral movement in various machine components while allowing for rotational motion.
Circlips are typically installed using circlip pliers, which expand the ring during installation and allow it to fit into a groove or housing.
TFC, a reputable supplier of a diverse range of fasteners, including circlips, caters to numerous applications. Our selection of circlip fasteners encompasses the following categories:
Types of Circlips
Circlips exhibit diverse shapes, designs, and sizes, each tailored to distinct application needs. Among the circlip options, TFC provides are:
Internal and External Circlips
Distinguishing these two variants is their application location. Internal circlips are employed in bores, while external circlips find use on shafts. These circlips often find application in motors, pistons, and turbines. Our assortment includes subcategories within internal and external circlips, including:
- Standard external circlips
- Lugged external circlips
- Standard internal circlips
- Lugged internal circlips
Lugged internal and external circlips are equipped with evenly spaced lugs to ensure optimal contact with radiused or chamfered components for bore sizes ranging from 16mm to 170mm.
Constant Section Retaining Clip
This circlip variant maintains a consistent section thickness from its centre to its ends. Installation, akin to internal and external circlips, necessitates circlip pliers.
Spiral Retention Rings
Manual installation is possible for spiral retention rings. These rings maintain a uniform section thickness and a 360-degree contact area. Their spiral shape provides a measure of shock absorption.
Tapered Section Circlip
The thickness of this circlip type tapers toward its ends, with the centre being the thickest and the ends being the thinnest. Circlip pliers aid in their installation.
Similar to tapered section circlips, inverted circlips possess inverted lugs. Installation methods mirror those of tapered section circlips.
K and E-Clips
K-clips exhibit a tapered section design with additional lugs, while E-Clips resemble the letter “E” and are inserted radially into shafts (not axially). E-Clips lack lugs, rendering them incompatible with circlip pliers. Conversely, K-clips, equipped with lugs, can be managed using circlip pliers.
Advantages of Utilising Circlips
In contrast to alternative fastening options available at TFC, circlips offer unique advantages. Some benefits include:
Circlips are designed to maintain their position even in high-speed applications. This stability ensures their effectiveness in dynamic parts, such as bearing wheels, by withstanding forces and contributing to safe machinery operation.
Certain circlip types, like external circlips, play a pivotal role in upholding consistent measurements for crucial machine parts. These circlips generate outward forces to preserve structural diameter, preventing malfunctions.
Circlips primarily serve to provide a secure grip on mechanical components. Particularly adept at this role, retention rings prove effective when correctly sized and chosen for the application.
Smooth Gear Function
In applications involving multiple moving parts like gears, circlips facilitate axial movement while maintaining gear alignment and preventing unwanted lateral displacement.
