An integrated pulley-torsional damper assembly ( 1 ) comprises a hub ( 2 ) designed for being rigidly connected to a drive member ( 3 ), a pulley ( 4 ) connected to the hub ( 2 ) by means of a first ring ( 5 ) made of elastomeric material having the function of filter for the torsional oscillations, and an inertia ring ( 6 ), connected to the hub ( 2 ) by means of a second ring ( 7 ) made of elastomeric material, which defines with the inertia ring ( 6 ) a damping system. The first elastomeric ring is connected to the hub by mans of a coupling flange ( 25 ), which can be pack-tightened between an internal annular flange ( 10 ) of the hub and the drive member ( 3 ), the hub ( 2 ) comprising a first cylindrical wall ( 11 ) and a second cylindrical wall ( 12 ), which are coaxial with respect to one another and define between them an annular cavity ( 9 ) housing the first elastomeric ring ( 5 ), the external cylindrical wall ( 12 ) defining a support for the second elastomeric ring ( 7 ).
