Each projection extends into a cooperatingly placed and shaped annular groove defined in the raceway of the respective inner and outer rings. Each projection and the sealing lip at its end has a lateral surface which is parallel to one of the lateral walls of the groove and is spaced therefrom. The sealing lip has a second, adjacent lateral surface which is parallel to a second adjacent wall of the groove and is spaced therefrom, providing a lengthened sealing slot. The end of the sealing lip rests against a third lateral wall of the groove which extends at least approximately parallel to the bearing axis.
