The invention relates to a sealing device for roll bearings in which a sealing element (9, 10) that interacts with a sealing surface is assigned to the rollpin (2). The aim of the invention is to improve a sealing device of this type so that a radial offset in the roll bearing results without significantly subjecting the sealing lip of the sealing element to stress. To this end, the sealing element is supported on the fixing device (8) thereof by means of an elastic supporting element (13), whereby the elastic supporting element has a rigidity less than that of the sealing lip (14, 15) of the sealing element.
