Internal Retaining Rings

Squeeze these rings to place them in the groove inside a bore or housing.

Heavy Duty Internal Retaining Rings

Thicker and stronger than standard internal retaining rings, these withstand greater thrust loads.

Inverted Internal Retaining Rings

For a smooth bore and better clearance than standard internal retaining rings, the lugs on these rings face outward.
