schell fasteners Germany schell models schell prices

schell 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 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, with conical surface plus retaining ring fixation offering higher centering accuracy. The retaining ring of a rolling bearing acts as a movable flange, used to guide rollers and facilitate installation.
