Cartridge sealing comprising an outer ring and an inner ring (1, 2) of opposite angular profile which together enclose an annular space (3) having a concentrically conceived axis (9), the outer ring (1) being provided with at least one sealing lip (4), which rests against the inner ring (2), the annular space (3) and the space sealed off communicating via a gap (5) bounded on one side by a flange (6) connected to the inner ring (2), the cross-section of the gap (5) being widened on the side facing away from the flange (6) in segmental cut-outs (7), distributed over the circumference of the outer ring (1), which form channels that connect the annular space (3) and the space to be sealed off, the channels being bounded in the axial direction, on the side facing the flange (6), by a conically sloping run-off surface (8) which forms part of a diameter concentrically surrounding the axis (9) and widened in a funnel shape in the direction of the annular space (3). In the axial direction, the run-off surface (8) surrounds the flange (6) completely and the sealing lip (4) at least partially. …<IMAGE>… |
