Abstract: A pulley (1) that is decoupled from the vibrations of a crankshaft and that has an integrated viscous torsional vibration damper (2), including a flywheel (3), which is arranged in a damper housing (5) that is filled with a viscous medium (4) and which can rotate relative to the housing, as well as a bearing (6) and a coupling (7) made of rubber elastic material, for supporting the pulley (1) with respect to the damper housing (5) in a flexible manner in the circumferential direction of the pulley and so as to be capable of relative rotation, the pulley (1) being assigned to the flywheel (3) so as to be axially adjoining. The damper housing (5) has at least one first axial projection (8), which is enclosed by the belt-bearing surface (9) of the pulley (1) at a radial clearance, and the bearing (6) is arranged in the gap (10) that is formed by the clearance.
