Sealing device for a wheel hub unit

A sealing device, comprising:

• a screen comprising a bottom wall coupled to a collar of a wheel hub unit;
• a cylindrical side wall integral and substantially perpendicular to the bottom wall, wherein a thickness of the cylindrical side wall is twice a thickness of the bottom wall;
• a stop edge comprising a surface facing the collar, wherein the stop edge is integral with the cylindrical side wall on an opposite side to the bottom wall, the stop edge configured to bear, during use, axially against the collar;
• a seat bound by a shaped groove formed in the collar and the screen, the seat comprising a closed shape;
• and
• a sealing gasket comprising a sealing liquid and applied to the surface of the stop edge, wherein the sealing liquid is anaerobic and formulated to fill and seal the seat, and the sealing liquid is configured to polymerize when closed between the collar and the screen,
• wherein,
• the seat comprises a first bottom surface and a second bottom surface,
• the first and second bottom surfaces face respective surfaces of the screen,
• the first and second bottom surfaces are inclined with respect to the respective surfaces of the screen,
• the second bottom surface faces the stop edge,
• the first and second bottom surfaces are adjacent to each other, and
• the first bottom surface comprises an extension smaller than an extension of the second bottom surface.
