External Circlips Manufacturer in China

External circlips are spring-metal retaining rings installed in an external groove on a shaft to prevent components from moving axially. The ring expands during installation and contracts into the shaft groove, creating a retaining shoulder for components such as bearings, gears, pulleys and hubs. The shaft diameter, groove diameter, groove width and ring cross-section determine the installed position and retaining condition.

As an external circlips manufacturer and factory in China, we produce standard and custom external retaining rings according to customer drawings, samples and specified dimensions. DIN 471 external circlips can be supplied in defined sizes and materials, while custom production can cover ring diameter, section thickness, groove fit, material, hardness and surface finish for shaft-specific requirements.
