Seal arrangement

A seal arrangement for a shaft having a broad rpm range, supported in a housing, in particular for axle drives, comprising:

• a radial shaft seal, configured to be arranged in a housing bore hole, for sealing a shaft bearing space against loss of lubricant;
• a baffle plate, joined to the shaft, having a lip seal aligned radially to the inside, the lip seal having a sealing surface, wherein under the effect of centrifugal force the lip seal lifts off from the sealing surface in response to higher rotational speeds of the shaft, and wherein the baffle plate at an exterior edge has an exterior ring, aligned with the radial shaft seal, an interior edge of the exterior ring, in cooperation with the polymer packing of the holding part, producing a labyrinth seal, and wherein the labyrinth seal is formed by a gap, oriented axially and radially, between a protruding ring bead of the holding part and a right-angle bend, aligned radially to the outside and resting inside the ring bead, on the interior edge of the exterior ring.
