Tapered rolling bearing (1) which presents an inner race (2) which is provided with a guiding rim (5) along one of its own sides; a ground rolling surface (7) which is radially obtained outside the inner race (2) and which is axially delimited by the guiding rim (5); a crown of tapered rollers (4), each of which is suitable for rolling in contact with the rolling surface (7) and which is extremely close to the guiding rim (5); and a grinding relief (8), which is obtained between the rolling surface (7) and the guiding rim (5) in order to permit the grinding of the rolling surface (7) itself, and which is provided with an annular outlet edge (9) which confines with the rolling surface (7); the annular outlet edge (9) of the grinding relief (8) being arranged at a determined distance from the rolling surface (7), said distance being measured transverse to the rolling surface (7) itself. |
