The fixation of axial parts is divided into axial fixation and circumferential fixation. The methods of axial fixation include: shoulder or ring fixation, end retainer or cone fixation, sleeve fixation, round nut fixation, and elastic retainer ring fixation.
The retaining ring mainly plays an axial fixing role, with the cone surface and retaining ring having a higher centering degree. The retaining ring of the rolling bearing is equivalent to a movable edge, used to file the rollers and facilitate installation. The structure of the retaining ring includes a flat retaining ring, a diagonal retaining ring, and a retaining ring
