Internal circlips are spring-metal retaining rings installed inside a machined groove in a bore or housing to prevent components from moving axially out of the assembly. The ring expands against the internal groove during installation, creating a retaining shoulder for components such as bearings, bushings, seals and other housed parts. The bore diameter, groove diameter, groove width and ring section determine the installed position and available axial retention.
As an internal circlips manufacturer in China, we produce standard and custom internal retaining rings according to customer drawings, samples and specified dimensions. DIN 472 internal circlips are available for standard bore applications, while custom production can be specified by bore diameter, groove dimensions, ring thickness, material, hardness and surface finish to match the housing and retaining requirements.
