A bearing (6) comprising an inner ring (2), an outer ring (3), and intermediate rotational means (4). The bearing further comprises a sealing device. The sealing device comprises a first seal (5) fitted between the inner and the outer ring of the bearing, comprising an axially extending annular lip (51), and a second seal (1). The second seal comprises a through shaft portion (12) extending into a bore of the inner ring, a radial portion (11) extending along the radial extension of the bearing, covering the inner ring and at least part of the first seal, and an annular groove (110) arranged to interact with the annular lip of the first seal so as to create a labyrinth seal between the first and second seal wherein the labyrinth seal seals a pocket (7) between the inner ring, the second seal, and the first seal. With this arrangement the bearing's service life is prolonged as the sealing device protects the bearing from contaminants entering into the bearing during rotation.
