About External Retaining Rings

Place these external retaining rings onto the outer surface of shafts to form a shoulder that holds components in place along the shaft while allowing rotation.

Wind these spiral rings into the groove on a shaft. They don't require any tools for installation and make full contact with the groove, leaving no gap.
