Bearing unit with rolling bodies

A bearing unit comprising:

• a radially outer ring comprising:
• at least one seat formed in a radially inner surface of the outer ring;
• and
• at least one cylindrical surface of the radially inner surface, each cylindrical surface being adjacent to a corresponding seat;
• a radially inner ring;
• a row of rolling bodies interposed between the radially outer ring and the radially inner ring;
• at least one sealing device interposed between the radially inner ring and the radially outer ring and comprising:
• a shaped shield comprising a metallic material;
• an elastomer coating overmolded on the shaped shield;
• and
• an anchorage formed on the elastomer coating and comprising:
• a radially external anchoring lip received by the seat of the radially outer ring and comprising:
• a root portion;
• and
• a projection distal to the root portion and comprising a flexibility and a thickness that is less than a flexibility and a thickness of the root portion;
• an annular cavity formed on a radially internal side of the anchoring lip, and
• a cylindrical portion comprising a radially external cylindrical surface, the cylindrical portion being axially spaced apart from the anchoring lip, the radially external cylindrical surface cooperating with a corresponding radially internal cylindrical surface of the at least one radially internal cylindrical surface of the radially outer ring;
• wherein an axial length of the annular cavity is greater than an axial length of the projection,
• the anchoring lip is flexed radially inward and at least partially fills the annular cavity.
