At least one row of rolling elements is disposed between the inner ring and the outer ring. A sealing assembly is disposed in at least one of the axial end portions of the rolling-element bearing. The sealing assembly includes a first sealing region disposed adjacent to the bearing rings, and a second sealing region spaced farther from the bearing rings than the first seal region. The first sealing region includes a lip seal, and the second sealing region includes a labyrinth seal. The internal volume surrounding the rolling elements located between the bearing rings is in fluid communication with the atmosphere.
