HOI-325ST PA, 3-1/4 in. Internal Inverted Ring .109 In. Thick Carbon Steel Black Phosphate

Inverted internal retaining ring in carbon steel, phosphate finish. Inverted retaining rings are a variation of axially assembled rings in which the lug holes are inverted to fit in the bottom of the groove. Inverting the lugs allows greater clearance on a shaft or in a housing and forms a higher uniform shoulder good for retaining bearings and other components with large corner radii or chamfers.
