External Retaining Ring Dimensions & Configurations

External retaining rings (also known as “external snap rings”) sit in the grooves on the exterior of shafts of any size. The areas of the ring that protrude out from the shaft hold it in place.

See below for our entire list of external retaining ring dimensions and configuration drawings.  If you do not see a ring that meets your specs, you can custom-design your own external snap ring right on our site!
