Circlip

A circlip, also known as a snap ring or clipsleeve, is a type of fastener used to secure a rod, shaft, or other object in place within a housing or bore. It consists of a circular or oval-shaped metal ring with a series of teeth or prongs on its inside edge. The circlip is designed to grip the rod or shaft firmly in place, holding it in position within the housing.

There are two main types of circlips: internal circlips, which fit over the rod or shaft from the internal side of the housing, and external circlips, which fit over the rod or shaft from the external side. Internal circlips are commonly used to secure rods or shafts in engine blocks, bearing housings, and other machinery components. External circlips are often used in applications where the rod or shaft must be removable for maintenance or repair.

Circlips are typically made from steel or other metal alloys, and are available in a range of sizes to accommodate different rod diameters. They are often used in conjunction with other fastening methods, such as bolts or screws, to secure rods or shafts in place.

The main advantage of using circlips is their ability to provide a secure and reliable connection between the rod or shaft and the housing. They are also relatively easy to install and remove, making them a popular choice for many applications. However, improper installation or over-tightening of the circlip can cause premature wear or damage to the rod or shaft, so proper installation and maintenance techniques must be followed.
