Abstract

The pressing wheel (1) comprises: - a rotational bearing (2, 3, 4) which comprises: - an inner annular element (2) associable with a support (20, 21, 22); - an outer annular element (3) arranged around the inner annular element (2) to define a first space (5); - a plurality of rolling elements (4) positioned between the inner annular element (2) and the outer annular element (3) and housed in the first space (5); - an outer rolling body (6) made of a polymeric material and supported by the outer annular element (3); wherein the outer rolling body (6) is co-molded on the outer annular element (3) and shaped to define two lateral annular flanges (7) adapted to cover at least part of the first space (5).
