Abstract
A seal assembly for sealing a radial rolling contact bearing, having a first sealing ring and a second sealing ring, wherein the two sealing rings can be rotated relative to each other about a common axis of rotation and together form a labyrinth seal, wherein a sealing gap of the labyrinth seal that extends substantially radially with respect to the axis of rotation is covered radially by an axial projection of the second sealing ring, and the sealing gap at the axial projection opens axially into a first catch channel of the first sealing ring. A hub of the radial rolling contact bearing forms the second sealing ring. Therefore, the second sealing ring is integrated into the hub flange, which means that the hub flange performs the function of the second sealing ring and to some extent helps to form the labyrinth seal.
