Abstract

A mounting device for a sealing ring, having a transport/mounting protective sleeve for the sealing ring and a sleeve-shaped punch with which the transport/mounting protective sleeve is movable on both sides in axial direction and automatically removable, wherein the protective sleeve has an inner step, extending axially, and an outside diameter corresponding to the outside diameter of a machine element to be sealed, and an axial length substantially corresponding to the axial length of the sealing ring, wherein the inner step is bounded axially counter to mounting direction by at least one end-side stop for the sealing ring, which stop forms part of an outer step likewise extending in the axial direction, wherein the outer step has a first driver surface with which at least one latching-lug-shaped driver of the punch can be engaged for automatic removal of the protective sleeve when the punch moves counter to the mounting direction.
