Retainer Rings
Retaining rings are metal fasteners that fit into a groove on a shaft or in a housing or bore to provide a shoulder that holds an assembly in place.
The purpose of a Retaining Ring is to act as a shoulder to stop the sub-component or assemblies coming off the shaft or housing bore, especially in mechanical power transmission assemblies.
A snap ring is a strong, thin, C-shaped metallic ring that works as a retaining fastener on shafts and inside circular bores to retain assembly parts. However, unlike a nut or bolt that threads onto a piece, a snap ring or C-clip snaps into a circular groove inside a bore housing or on the shaft. That is why it is called a snap ring because it has high tensile strength that makes it snap into the radial groove and stay in place.
Once the ring fastener sits properly in the groove, part of its circumference sticks out to form a shoulder that secures the assemblies inside the housing or onto the shaft. This is why snap rings are also called retaining rings because they retain components in an assembly.
