Antifriction bearing with improved seal

The bearing has a rotating inner ring (2) provided with a sealing wall (22) rotated axially toward bearing paths (21, 31). The sealing wall extends radially toward outside by an annular edge rotated toward outside. An outer ring (3) is provided with a cover wall (32) comprising an axial overlap length (e) with the edge for radially forming an outer annular opening (10). The inner ring comprises an annular gutter (8) rotated radially toward outside, where the edge is situated between the gutter and the wall. A multi-lever sealing joint is formed in a sealing chamber (7) between the rings.
