RS PRO Stainless Steel External Circlip, 18mm Shaft Diameter, 17mm Groove Diameter

Use these RS PRO external circlips to fit a mechanical part securely to a shaft without interfering with its continuous rotational force. They're supplied in a pack of 50 and come with a storage box for easy organisation.


The external circlips fit into a groove on the outside of the shaft. This helps to retain them and keep them secure against high rotational speeds. If you need to install or remove them, all you need are RS PRO circlip pliers. They come with a layout sheet detailing dimensional information for quick reference.


Retaining rings like these are often used in applications involving turning parts, such as electric motors or roller bearings. Their stainless steel material makes them resistant to corrosion, so they're suitable for use outdoors.
