RS PRO circlip kit which contains a range of circlips including E Type circlips, External circlips and Internal circlips.
Circlips (also known as retaining rings) are types of fastener which look like flexible, open-ended rings. Circlips are typically made from stainless steel and similar metals. Alternative names for circlips include retaining rings, retaining clips, C-type, Jesus clips, snap rings, and E-type.
Circlips come in two main types – internal and external. An external circlip is designed to fit around a bore, whereas internal circlips are made to fit inside a cylindrical shaft or housing.
It is always important to choose the right circlip sizes for the job at hand. The retaining ring must be suitable to fit inside the shaft where it will be installed (internal circlips) or should fit snugly around the outside of the housing (external circlips). If the retaining ring is incorrectly sized, the installation will be significantly more challenging, and it may lead to further problems in the future if left unchecked.

FAQs
How Do You Measure External Circlip Size?
When measuring the size of an external circlip, you should measure the nominal size of the groove diameter. Do not measure the shaft diameter as this will result in an inaccurate measurement when comparing external circlip sizes.

How Do You Measure Internal Circlip Size?
To accurately measure the size of an internal circlip, you will need to measure the nominal size of the groove diameter. Avoid measuring the bore diameter as this will not provide the correct size.
