Circlips are generally deployed where components are required to be kept fitted on shafts or housings, as well as with a range of bearings used in mechanisms designed to twist, spin, turn, rotate, or pivot. The key selling point of C-clips is that they allow for the easy rotation of shafts and dowel pins when installed. They also prevent lateral (sideways) movement as a result of their unique design and shape, which acts as a self-locking mechanism once installed around a suitable part.
Circlips themselves tend to have open ends, rather than being a complete ring. This open-ended ‘horseshoe’ design gives them a certain amount of spring tension. Once fitted in place, the spring pressure effect ensures that they don’t move or slip out of place.
The majority of circlips feature a small hole in a lug at either end, which allows for the installation or removal of the circlip plier tips. Circlip pliers, or circlip removers, are therefore an essential piece of kit for anyone who works regularly with this type of fastener.
