freres pagnin fasteners, Germany freres pagnin models, freres pagnin prices

freres pagnin fasteners are installed in shaft grooves or bore grooves of machines and equipment to prevent lateral movement of components on the shaft or in the bore. Fixation of shaft components is divided into axial fixation and circumferential fixation. Methods for axial fixation include: fixation by shaft shoulders or collars, fixation by shaft end retaining rings or conical surfaces, fixation by sleeves, fixation by round nuts, and fixation by elastic retaining rings. Retaining rings primarily serve for axial fixation; among these, fixation using a conical surface with a retaining ring offers high centering accuracy. The retaining ring of a rolling bearing acts as a movable shoulder to retain the rollers.
