ABSTRACT:
A sealing arrangement for roll bearings in skin pass mill stands in which the roll neck has a tapered portion extending between the end face of the roll and a portion of the roll neck which is provided with a neck sleeve and is supported in a bearing bushing in the bearing housing. An annular, flexible sealing member constructed in one piece and reinforced by means of an annular wire rope or strip is slid onto the tapered portion of the roll neck and rests on the tapered portion with annular sealing projections. An outer annular end of at least one of two axially spaced radially extending, elastic annular ribs can be placed in elastic frictional contact with at least one annular sealing surface which is rigidly connected to the lid of a housing and is arranged laterally of an annular flange rigidly connected to the housing. The second annular rib on the side of the roll is a rib stump whose circumference has the shape of a truncated cone. The rib stump has a sharp tear-off edge facing the annular flange.
