- 1A - ABSTRACT A bearing assembly has two relatively rotatable members formed with annular tongues which are interleaved to form a labyrinth passageway seal between the two members. At least a portion of the passageway is defined by frusto conical surfaces on the annular tongues arranged to exert centrifugal force on any foreign matter in the passageway upon relative rotation between the two members so as to urge the foreign matter towards the outer end of the passageway. The labyrinth passageway may comprise portions which are flared in the direction towards the outer end of the passageway, and the annular tongues on one of the members arranged eccentric or non-circular so that the two members exert a pumping action on any foreign matter in the flared portions of the labyrinth passageway upon relative rotation between the two members.
