stumpp+schule fasteners Germany stumpp+schule model stumpp+schule price

stumpp+schule 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 end rings or conical surfaces, fixation by sleeves, fixation by round nuts, and fixation by elastic retaining rings. Retaining rings primarily serve for axial fixation; fixation using a conical surface with a retaining ring provides high centering accuracy. The retaining ring of a rolling bearing acts as a movable shoulder to guide the rollers.
