Internal snap rings are used to:

Internal snap rings sit inside a bore and bite into an internal groove, creating a shoulder that stops components from moving axially out of the casting. This lets parts such as bearings, sleeves, or shafts stay securely in place within the bore, which is the core reason they’re used. They’re not primarily seals, so they don’t stop oil leaks, and while they have a ready-made spring-like character, their main purpose isn’t to provide a spring force. External snap rings serve retention on shafts instead of inside bores.
