A hub-bearing assembly for agricultural use having a rolling bearing, a housing, a closing cap and an axial retention feature. The roller bearing includes an outer ring, at least one inner ring, at least a row of rolling bodies and a sealing device. The housing includes an almost annular cylindrical shape, the housing at one end forming a radial flange, containing the rolling bearing and being in direct contact with the bearing outer ring. The closing cap is assembled on the housing at the opposite end with respect to the end, where the housing forms the flange. It is noted that the cap is cup shaped. The axial retention feature is located along an external surface of the outer ring. The retention feature is located opposed to the axial sliding of the outer ring with respect to the housing. |

1. A hub-bearing assembly comprising:
a rolling bearing including an outer ring, at least one inner ring, at least one row of rolling bodies and a sealing device; a housing having an almost annular cylindrical shape, the housing at one end forming a radial flange, containing the rolling bearing and being in direct contact with the bearing outer ring; a closing cap, assembled on the housing at the opposite end with respect to the one end, where the housing forms the flange, the cap being cup shaped; and an axial retention feature, which are located along an external surface of the outer ring, said retention means being opposed to the axial sliding of the outer ring with respect to the housing, wherein said axial retention feature comprises a retention ring, which is assembled with radial interference on the bearing outer ring, the retention ring presenting a section, substantially “L” shaped, having a substantially radially extended wing, which provides the ring with mechanical resistance, wherein the housing is made of plastic material and is co-molded on the outer ring of the rolling bearing, wherein the substantially radially extended wing separates the outer ring from the sealing device. |
