Circlips and E Clips

Here at Townsend Bearings we supply an extensive range of both internal and external Circlips as well as E clips available in both imperial and metric sizes from stock.

A circlip, which is also known as a snap ring, is a type of fastener consisting of a semi-flexible metal ring with open ends which can be snapped into a machined groove, on a dowel pin or other part to prevent lateral movement but permit rotation.

There are two basic types of circlip: internal and external. External circlips are fitted over a shaft and are sized relative to the recommended shaft size to which they are to be fitted.


Internal circlips are fitted into a bore and are sized relative to the bore into which they fit (not the diameter of the groove). It is assumed the circlip groove in the shaft is to usual standard dimensions. An E-clip allows for a much wider range of shaft size and is sized according to the groove diameter into which it is fitted.
