Claims9
A seal comprising a sealing ring (1) and a slide ring (2) wherein the slide ring (2) is provided on the side of the sealing ring (1) that faces the surface to be sealed, characterized in that the sealing ring (1) and the slide ring (2) are formed in one piece.
A procedure for producing a seal characterized in that, in a first step of the procedure, a cylindrical tube section (5) of a polymeric material of a slide ring (2) is placed in a tool cavity (6) of a manufacturing tool (7) and held in its position, the tube section (5) dividing the tool cavity (6) in radial direction into a slide ring cavity (8) and a sealing ring cavity (9) that are radially adjacent, and the tube section (5) comprising an axial width (10) that substantially corresponds to the axial width (11) of the tool cavity (6), in that, in a second step of the procedure, elastomeric material is pressed into the sealing ring cavity (9) in such a way that the elastomeric material completely fills the sealing ring cavity (9) and molds the tube section (5) radially into the slide ring cavity (8) until the tube section (5) comes to rest against the wall (12) that delimits the slide ring cavity (8), and in that in another step of the procedure the seal is removed from the manufacturing tool (7).
