A sealing arrangement comprising a one-piece, peripheral, elastomeric sealing material for sealing a sealing space, the material containing a bearing-side sealing region and inserted between at least one outer rotatable bearing component and, mutually rotatable about the same center axis, at least one inner rotatable bearing component of a rotary joint, wherein the sealing arrangement is form-lockingly and force-lockingly connected in a detachable and replaceable manner to a structure, namely (I) to a plunge cut in a surface parallel to a horizontal outer surface of one of the inner and outer rotatable bearing components, and (II) to a projecting material protrusion with a bottom surface which is disposed on the bearing side of this material protrusion, as an integral part of the inner or outer rotatable bearing component.

Peripheral sealing arrangement

The invention relates to an element () for sealing two parts () that can be rotated in relation to one another. Said element comprises at least one first sealing ring () consisting of a permanently elastic material, which is fixed to one of the two rotatable parts and comprises at least one sealing lip () and at least one second sealing ring (), which is fixed to the other rotatable part and comprises a strip () consisting of another material that runs along its periphery. At least one sealing lip of the first sealing ring lies against said strip.
