ABSTRACT:
A device for sealing a spherical rolling bearing comprises two annular sealing bodies (4, 5) arranged on the respective bearing rings and divided by a gap (6) with spherical opposing surfaces. A further sealing washer (9) is provided in recesses (7, 8) in the sealing bodies (4, 5) and delimits a space (10) in connection to the gap (6). The washer (9) is fixed in one sealing member (4) and is provided with a sealing lip (11) contacting a spherical surface of the other sealing body (5). The device gives a good sealing effect also when the rings of the bearing are skewed in relation to each other.
