Claim 6:
7. A bearing unit comprising:
a stationary radially outer ring;
a radially inner ring, rotatable with respect to a rotation axis (X) and connected to a rotating shaft;
a row of rolling bodies interposed between the radially outer ring and the radially inner ring;
a casing housing the radially outer ring and the radially inner ring;
a sealing device; and
a protection disk, mounted in an axially external position to the sealing device and fixed to the radially inner ring, the protection disk comprising a shaped metallic screen, and an elastomer coating co-molded on part of the screen,
wherein the protection disc is in contact with an axially external surface of the radially outer ring through the elastomer coating, wherein the elastomer coating is provided with a first lip and a second lip, wherein the first lip is radially external and is configured to be one of non-contacting and contacting with the axially external surface of the radially outer ring; and the second lip is radially internal and configured to contact the axially external surface of the radially outer ring,
wherein the screen comprises:
a cylindrical portion configured to couple by interference with the radially inner ring,
a distal portion oblique in a radially external and axially internal direction, wherein the elastomer coating is co-molded on the distal portion,
a first flange portion connected to the distal portion,
a second flange portion, connected to the cylindrical portion, and
an oblique portion configured to connect the first flange portion and the second flange portion.
