Abstract
A ball bearing having a cage which on its opposite axial ends has respective radially inward, obliquely axially outwardly and radially inwardly directed projections and has respective radially outward, obliquely axially outwardly and radially outwardly directed projections. 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.
