External retaining rings are a ring shaped stamping with one opening on the circumference. The two ends at the opening are called lugs and flare out slightly allowing for easier installation onto shafts.

The external retaining ring is for axial assembly into machined grooves on shafts. Tapered section design assures uniform circular deformation, allowing for complete contact and tightness in groove. Steel rings can be safely used within a temperature range of -100°F to 500°F. Stainless steel rings are corrosion resistant and can be used in higher heat applications from -100°F to 900°F.
