A vibration damping system for a rolling mill comprising a rolling cage and a bending adjustment system (3, 3', 17, 18, 21, 21' and 22, 22' and 23, 23' and 24, 24') of the rollers (1, 1'), comprising hydraulic actuators (21, 21' and 22, 22' and 23, 23' and 24, 24') acting on the rollers (1, 1') and hydraulic circuits (18, 19) for feeding, and hydraulic damping means ((25, 31, 32), (27, 28, 45, 46, 42), (29, 30, 56, 58, 59, 70)) of a force (Fv), connected to the hydraulic circuits (18, 19) for actuating a damping effect by means of the hydraulic actuators (21, 21' and 22, 22' and 23, 23' and 24, 24'). The hydraulic damping means may comprise a pair of hydraulic pumps (25B, 25C, 45B, 45C) or a pair of hydraulic cylinders (59, 69) with a dual chamber, connected in an opposite direction to each other to the hydraulic circuits (18, 19). |
