Circlips, also called retaining rings or snap rings, are circular fastener types used to secure components on a shaft or in a housing bore. They are typically made of semi-flexible metals with open ends rather than a complete circle. Circlip ends are designed to fit into grooves or recesses on the shaft or inside a bore, effectively preventing the axial movement of the securing components. The primary advantage of using circlips, including E-clips, is their ability to hold components in place while allowing for easy assembly and disassembly. They eliminate the need for threading or other complex fastening methods. Moreover, circlips come in various sizes, designs, and materials to accommodate different applications. Additionally, retaining rings feature a miniature hole at either end for their effortless insertion or removal.
Prominent Benefits of Using Circlips
Circlips offer numerous benefits in terms of space efficiency, cost-effectiveness, and ease of installation. These retaining rings are versatile components with unparalleled applications in multiple industrial facilities. Additionally, they are made of robust materials with stable and secure retaining part functionalities within assemblies.
What are Circlip Pliers?
A circlip plier is a hand tool used to remove or install circlips easily. Circlips comprise compatible and specific-sized tips to fit into the corresponding circlip's holes. These pliers come in varied types specifically designed for various circlip types. For instance, internal and external circlip pliers can easily remove or insert a compatible circlip type with great flexibility and accuracy.
Popular Types of Circlips
Circlips come in varied types based on shape, fitting place, and materials. Some popular circlip types include:
- Internal Circlips – These are installed inside a bore or housing. They exert outward pressure against the bore, preventing components from moving in the axial direction.
- External Circlips – These are fitted around a shaft or spindle and exert inward pressure against the shaft. The exerted pressure prevents components from sliding off the end.
- E-Clips – The "E-clip" variant gets its name from its shape–resembling the letter "E." E-type circlips have two open ends and are usually used in grooves on shafts or inside bores to secure components such as bearings, gears, or pulleys.
Other Circlip Types Include
- Stainless Steel Circlips
- Tapered Section Circlip
- Inverted Circlip
- Star or K-Circlip
