Wheel hub bearing assembly with sealing device

A wheel hub bearing assembly comprising:

• a flanged inner ring rotatable about a central axis;
• a stationary outer ring disposed about the inner ring such that a gap is defined between the inner and outer rings, the outer ring being provided with a tubular end collar delimited axially toward the outside by an annular abutment surface;
• a sealing device coupled with the tubular end collar and including a shield, the shield having a cylindrical lateral mounting wall keyed into the tubular end collar and an annularly extending annular stop edge integral with the cylindrical lateral mounting wall and bearing axially against the annular abutment surface, a sealing fluid applied in an application zone located between the tubular end collar and the annularly extending annular stop edge;
• and
• at least one annular groove formed in the abutment surface of the tubular end collar and/or in the stop edge of the shield, extending circumferentially about the axis, spaced radially outwardly from the application zone and being configured to collect any sealing fluid escaping from the application zone.
