Circlips

MATERIAL AND USES

Circlips are a type of fastener used to secure components on a shaft or in a bore. They are typically made of various materials, depending on the application requirements.

Circlips are commonly manufactured from the following materials:

Stainless steel:

circlips offer superior corrosion resistance compared to carbon steel. They are often used in environments where exposure to moisture, chemicals, or high temperatures is expected. Stainless steel circlips are available in different grades, such as 304 and 316, each offering varying levels of corrosion.

Carbon Spring Steel:

This is the most commonly used material for circlips due to its excellent strength and elasticity. Carbon spring steel provides good resistance to corrosion and is suitable for many general-purpose applications.

Types

A-Type Circlips: A-type circlips are also known as external circlips. They are designed to fit into grooves on the outside diameter of a shaft. These circlips have an open-ended, C-shaped configuration, with the ends of the clip protruding outwards. A-type circlips exert an outward radial force against the groove walls, securing the component or assembly in place.

B-Type Circlips:B-type circlips are also referred to as internal circlips. Unlike A-type circlips, they fit inside a bore or housing, utilizing the space between the shaft and the bore wall. B-type circlips have a closed circular shape and feature two lugs or tangs that can be squeezed together during installation to fit into a groove. Once in position, the lugs expand to hold the circlip securely within the housing, preventing axial movement of the components.

C-Type Circips: C-type circlips are a variation of external circlips with a slightly different shape. They have a more rectangular or square profile compared to the C-shaped design of A-type circlips. C-type circlips also fit into grooves on the outside diameter of a shaft but provide a more uniform and continuous 360-degree contact with the groove walls. This design helps distribute the radial forces more evenly, providing enhanced stability and load-bearing capabilities.

The selection of circlip type depends on the specific application and the design requirements. A-type circlips are commonly used for securing components on shafts, while B-type circlips are suitable for holding components within bores or housings. C-type circlips, with their improved load distribution, can be used in applications where higher strength and stability are needed.
