<h1>Snap Ring</h1>
Snap ring can also be termed as circlip rings, is a robust, thin, C-shaped metallic ring used as a holding fastener on shafts and within circular bores to hold assembly elements in place. Snap ring does not work like a nut or a bolt which mainly thread into a component, snap ring has a different function, it snaps into the groove within a housing or on the shaft. Snap ring has great structural integrity having good strength properties and therefore it can snap into groove and hence referred to as snap ring. Snap rings are also sometimes termed as retaining rings because of the ability to hold the elements in the assembly. There are various types of snap rings, but mainly they are differentiated into two they are external snap rings and internal snap rings.
For installing snap rings within a hole or housing, at first it is compressed by pulling the ends and then it is pushed into the slot, this installation can be done manually by hand or by snap ring pliers. Snap ring pliers are tools that are designed to fix and detach snap rings. These are distinct from conventional pliers such that they feature an uniquely made tip for working with snap rings. Snap rings have open-end design, due to this there is spring pressure, this spring pressure action stops the snap ring from sliding or shifting, and that is why snap rings are mostly used in machinery slots for keeping all elements at their places in shaft. They provide a fast and safe technique to join mechanical components. Materials such as carbon steel, beryllium copper, vanadium chrome steel alloy are used for snap rings. These materials have great strength properties, and they are able to tolerate high pressure and heat. External snap rings, are at the outer side of the shaft in such a way that they are wrapped around the shaft and their purpose is to keep shaft assemblies in place, whereas internal snap rings are fitted inside a bore or housing to prevent assemblies or parts from falling out. Snap rings are measured by vernier callipers.
