Internal Retaining Ring Dimensions and Configurations

Proper fit of an internal retaining ring is incredibly important. These rings fit into numerous components and housings. As radial tension in the component builds, the internal retaining ring will push it away from the center to the walls. This allows the piece to stay in its place.

See below for our entire list of standard internal retaining rings, including our internal retaining ring dimensions and configuration drawings.

Other options include Bowed Retaining Rings, Beveled Retaining Rings, Push-On Retaining Rings and Balanced Lug. If you need Standard External Retaining Rings, we offer those in copper and carbon steel finishes as well.
