A cassette seal for a shaft passing between a clean lubricated space and an environmentally dirty area outside the space and for sealing the space against ingress of contamination from the outside, which comprises an inner ring and an embracing outer ring which are inseparably linked to one another. The outer ring carries a main seal that bears on the inner ring and the outer ring includes an annular recess, which is at least partly overlapped by an annular radial projection on the inner ring and in which a backup seal is attached to the projection and extends into the recess. The backup seal has two sealing lips bearing respectively on radially inner and outer surfaces of the recess with the second lip extending from the front of the first lip but in the opposite axial direction.
