The sleeve comprises a central tubular core (1), designed to be coupled onto a shaft, and a stratified structure (2) arranged on an outer surface of said tubular core (1). The stratified structure (2) comprises a plurality of strata of a high-density component that are overlaid radially and separated axially, forming helicoidal or discoidal high-density ribs (3b), a low-density component filling in spaces separating the aforesaid high-density ribs (3b), forming a low-density fill (4), and a plurality of strata of a high-density component overlaid radially, forming a continuous high-density outer layer (3c) supported on said high-density ribs (3b) and on said low-density fill (4).
