The subject of the invention is the construction of a device for balancing an industrial fan shaft with an increased rotational speed of up to 1500 rpm, enabling shortening the time of its balancing process. The device for balancing the shaft of an industrial fan consists of a two-piece inner ring (1) to be mounted on the balanced shaft and two identical, parallel balancing rings (2, 2') with balancing masses (3, 3') located on the inner ring (1) coaxially. Around the balancing rings (2, 2') there are two identical, coaxial stators (A, A'). The balancing rings (2 and 2') are connected to the inner ring (1) independently, in a movable way, through two drive units (4, 4') and have a drive disc (7) located perpendicularly to the common axis of the stators (A, A' ) and shifted relative to the middle planes of the stators (A, A'), and the upper surface of the drive disc (7) is spaced from the inner surfaces of the stators (A, A') by the air gap (14).
