Accordingly, the roller has at least one zone experiencing high wear stress Z1, with at least one portion of the insert positioned at a distance d1 near the work surface of said roller; and a zone with low wear stress Z2, with a portion of the insert positioned at a distance d2 that is set back relative to the work surface of the roller.
