What are the types and functions of the retaining rings in the rubber combination seals?

The sealing element has a seal called a stop ring, which can be combined with the rubber seal to form a combined seal ring. And simply put, it has a certain blocking effect. It is usually used for bearings, shafts and buried-hole bases. Its main function is to avoid the bearing and shaft falling off, fix the shaft or the bearing moving horizontally to meet the working conditions.

(A) There are also different types of rings:

1. Elasticity for shaft

a) Single-hole shaft

b) Double-hole shaft

2. The elasticity of the reverse axis

Generally divided into hole stop ring and shaft stop ring, positioning effect, can prevent other parts from axial movement. The molding process mainly adopts plate cutting, the functional cross-section is conical, after installation, mainly for the "line touch" part of the large model, the use of cable winding molding, cutting excess material, the piston seal cross-section is a standard rectangle, after installation, the "surface contact".

(2) Purposes

Retainer seals usually play the role of axial fixation, in which conical and retainer fixation have higher centrality. Shaft components can be used for axial and axial fixation (shaft shoulder or shaft ring fixation, shaft end retaining ring or cone fixation, shaft sleeve fixation, round nut fixation, elastic retaining ring fixation)
