摘要： A roller bearing including an outer ring, at least one inner ring and a plurality of rolling bodies inserted between the outer ring and the inner ring. The outer ring presents an osculation of between 0.51 and 0.56 and the inner ring presents an annular race having a bottom surface delimited by an annular relief (16) including a cylindrical section (18) with a greater diameter than that of the bottom surface (12), a first convex curved section (19) having a pre-established radius of curvature (R1) and which connects with continuity the annular bottom surface (12) of the first annular race with the cylindrical section (18), a second convex curved section (20) which connects with continuity with the cylindrical section (18) and a third concave curved section (21) that connects with continuity with the second section (20).
