ABSTRACT:
A seal for use on the tapered section of a roll neck in a rolling mill. The seal has a flexible circular body with a circular lip and a circular flange at one end thereof. The lip extends axially from the body and the flange extends radially from the body and normal or perpendicular with respect to the body axis when the seal is in an unstressed condition. The seal is adapted to be axially received on and to be radially stressed by the tapered roll neck section with an accompanying radial expansion of the lip which produces a circumferential bending moment tending to angularly distort the flange from its perpendicular orientation to the seal axis. An internal circular shoulder on the seal body, coacts with the tapered roll neck section to counteract the bending moment and thereby prevent distortion of the flange.
