The roller comprises a rotation axis (A-A), an outer sleeve (35) that is hollow inside, and a pair of side pads (40A, 40B). Each pad comprises a support and rotation journal (43A, 43B) for the roller, and a body (41A, 41B) integral with the support and rotation journal. The peripheral surface of the body (41A, 41B) of each pad (40A, 40B) has an axial dimension (A1) at least equal to a transverse dimension (D1) of the body. |
