caption_attribution_description: English: A collection of the most common types of axially installed retaining rings
context_page_description: A retaining ring is a fastener that holds components or assemblies onto a shaft or in a housing/bore when installed - typically in a groove - for one time use only. Once installed, the exposed portion acts as a shoulder which retains the specific component or assembly. Circlips are a type of retaining ring.
  Circular push-on retaining rings may be installed in applications where there is no groove.
  Retaining rings are typically made from carbon steel, stainless steel or beryllium copper and may feature a variety of finishes for aesthetics and corrosion protection depending on the type of environment in which they are used.
context_section_description: Tapered section retaining rings decrease symmetrically from the center to the free ends, remaining circular when contracted or expanded within the limits of normal use.  This assures contact with the groove along the entire periphery of the ring.  These rings may be installed axially (horizontally along the center point of an axis) or radially (externally along the radius of a circle).  Depending on the size of the ring in question, it may be manufactured in one of two ways: 
  For smaller rings: using a die and stamping on a press from a coil of steel or copper
  For larger rings: wire forming, in which rectangular wire is coiled into the shape of the ring.
