A bearing assembly includes at least two bearings each having an inner ring and outer ring, the inner rings being mounted on a shaft, and a balancing piston being disposed between the two bearings. The balancing piston includes a first part and a second part, the first and second parts each contacting the outer rings of the two bearings in an axial direction. The balancing piston further includes an inlet for directing a pressure fluid between the first and second parts to provide pressure to the first and second parts such that the balancing piston adjusts or exerts axial force on at least one of the two bearings. The balancing piston includes an outlet for directing the pressure fluid to lubricate at least one of the two bearings. Also, the outer diameter of the balancing piston is greater than the outer diameter of the outer rings of the two bearings.
