Overview
The Rotor Clip HO-193ST PA is a tapered-section internal circlip engineered for precision bore retention in motors, pumps, gearboxes, and other rotating equipment. This snap ring is designed to install into a housing groove and prevent axial movement of components along the bore. The HO-193ST PA model represents Rotor Clip’s quality standard for internal retaining rings used across industrial machinery, automotive, and fluid power applications.
