Abstract

A sealing device for bearing units is disclosed herein. The sealing device may comprise a static component and a dynamic component. The static component is provided with a shaped metal support, with a plurality of non-contacting sealing lips, and with two contacting lips. The dynamic component defines a labyrinth seal with a second sealing lip of said non-contacting sealing lips, a third lip, preferably non-contacting, being positioned along the labyrinth seal and having a full angular extension, so as to form a full seal against any ingress of contaminants into the bearing unit.
