A sealing ring includes: a first axial leg; and a sealing leg with a sealing lip. When viewed in cross section, the sealing ring is in a shape of a seven. The sealing leg is connected to a first end face of the first axial leg by a first joint. The sealing leg has, on a side facing axially toward the first end face, a dirt lip with at least one sealing edge and a radially internal first boundary surface and a radially external second boundary surface.

Sealing ring and use thereof

A friction welding tool having a pin and a clamping device with a counter bearing, a holddown element and a spring element. The pin has a coupling section for releasable, rotationally fixed coupling to a rotating output device of a machine tool. The counter bearing is held on the pin between the pin's coupling and engagement ends in a manner that allows the counter bearing to be axially immovable on but freely rotatable about a longitudinal axis of the pin. The holddown element surrounds the pin and is arranged on a side of the counter bearing facing the engagement end. The holddown element has a bearing surface for bearing on the workpiece arrangement. The spring element is provided between the holddown element and the counter bearing and is mounted on the pin in such a way that it is elastically slidable along the longitudinal axis of the pin.
