les ressorts wilfart fasteners are installed in shaft grooves or bore grooves of machines and equipment, serving to prevent lateral movement of components on the shaft or in the bore. Fixation of shaft-mounted components is categorized into axial fixation and circumferential fixation. Methods for axial fixation include: fixation using shaft shoulders or collars, fixation using shaft end retaining rings or conical surfaces, fixation using sleeves, fixation using round nuts, and fixation using elastic retaining rings. Retaining rings primarily serve for axial fixation; among these, fixation using a conical surface with a retaining ring offers higher centering accuracy. The retaining ring of a rolling bearing functions as a movable shoulder.
