Snap-on sealing ring for externally sealing a shaft connection

An axially clamped face serration assembly, comprising:

• a first component comprising a first face serration;
• a second component comprising a second face serration, the first face serration and the second face serration being in toothing engagement with one another and being axially clamped to one another;
• and
• a snap-on sealing ring surrounding the first face serration and the second face serration radially on an outside and sealing the same;
• the snap-on sealing ring being pressed onto a shaft step at the first component by way of a metallic contact surface of a sleeve-shaped connecting section of a metallic insert;
• the snap-on sealing ring engaging, with axial play, in one or more recesses at the second component by way of at least one catch lug of a plastic base body;
• and
• the snap-on sealing ring further comprising, at an axial end face, a circumferential sealing surface configured to bear against the second component or against a sealing element arranged thereon when a backlash-free assembly position of the first and second face serrations is reached.

A non-contact wheel bearing pre-seal assembly, comprising:

• a wheel carrier;
• at least one of a wheel hub, a wheel bearing, and a journal;
• and
• a snap-on sealing ring mounted to the wheel hub, the wheel bearing, or the journal, the snap-on sealing ring comprising a plastic base body and a metallic insert, the snap-on sealing ring being retained by at least one catch lug engaging a corresponding recess of the hub, bearing, or journal, the snap-on sealing ring further comprising a flange section that cooperates with a mating contour of the wheel carrier or of a component attached to the wheel carrier to define a non-contact sealing gap configured to inhibit ingress of moisture and contaminants into the wheel bearing.
