Purpose of Backup Ring:

(1) The fixing of parts on the shaft is divided into axial fixing and circumferential fixing;

(2) The methods of axial fixing include: shaft shoulder or collar fixing, shaft end backup ring or conical surface fixing, shaft sleeve fixing, round nut fixing, elastic backup ring fixing;

(3) The backup ring mainly plays the role of axial fixation, in which the conical surface and the backup ring are fixed with a higher centering degree;

(4) The backup ring of the rolling bearing is equivalent to a movable rib, which is used to block the rollers and is convenient for installation. The structure of the backup ring includes a flat backup ring, an oblique backup ring and a middle backup ring.
