A retaining ring is a fastening component that securely holds parts in position on a shaft (external) or within a housing/bore (internal) in mechanical assemblies. Creating an artificial shoulder or joining two components together, retaining rings offer minimal surface preparation and reduced mass compared to cotter pins and bolts. Retaining rings are particularly useful in applications where axial force is present, preventing unwanted movement and maintaining alignment. They provide a cost-effective and efficient solution for secure fastening across various industries, including automotive, military, medical, aerospace, energy and beyond. There are many styles and names of retaining rings, each with their own unique properties and advantages: tapered section/circlip, constant section/snap ring, spiral rings,  e-rings, c-clips and more. Learn about the differing styles of rings Rotor Clip produces.
