What Is the Function of Retaining Ring?

The fixing of shaft parts is divided into axial fixing and circumferential fixing.

Axial fixing methods are: shaft shoulder or shaft ring fixed, fixed with shaft end retaining ring or taper, fixed with sleeve, fixed with round nut, fixed with elastic retaining ring.

Retaining ring is mainly to play the role of axial fixing, which taper plus retaining ring fixed with a high degree of centering.

Rolling bearing retaining ring is equivalent to a movable retaining edge, is used to file the rollers with, convenient installation. The structure of the retaining ring has flat retaining ring, oblique retaining ring and middle retaining ring.

What are the classifications of retaining rings for shafts?

✔️According to its role

Flat retaining ring: a separable basically flat gasket, its inner or outer part used as the outer ring or inner ring retaining edge of the radial cylindrical roller bearing.

Oblique retaining ring: with "L" shaped section of the separable ring, the outer part of its role for the inner edge of the radial roller ball bearing.

In the retaining ring: two or more rows of roller bearings in the separable circle, used to separate and guide each row of rollers.

Retaining edge is parallel to the rolling direction and protrude from the raceway surface of the narrow convex shoulder, used to support and guide the rolling body and make it keep in the bearing.

✔️Other classification

Retaining ring has: taper pin locking retaining ring, screw locking retaining ring, screw locking retaining ring with locking ring, steel wire retaining ring, hole with elastic retaining ring - A type, hole with elastic retaining ring - B type, shaft with elastic retaining ring - A type, shaft with elastic retaining ring - B type, screw fastening shaft end retaining ring, bolt fastening shaft end retaining ring, hole with steel wire retaining ring, shaft with steel wire retaining ring, etc.
