Abstract
A sealing device for sealing a bearing unit against external contaminants is arranged substantially inside a cavity of the bearing unit and is provided with two annular metal screens and a sealing element made of elastomeric material. The sealing element is rigidly connected to a rotary one of the two annular screens and is provided with a shaped protrusion projecting radially outwardly from a stationary one of the two annular screens to define, together with the stationary screen, an annular opening of the sealing device. The stationary screen and the sealing element also together defining a drainage and flow channel in communication with the outside of the sealing device through the annular opening, in which the drainage and flow channel is entirely linear and extends in an exclusively radial direction within the sealing device to and from the opening.
