The utility model discloses a small-volume vertical type hydrapulper axle device, comprising a bearing chamber, a main axle in the bearing chamber, a spherical-roller bearing sleeved with the main axle and arranged at the position of the bearing chamber near to the bottom, a withdrawl sleeve arranged in the spherical-roller bearing and sleeved with the main axle, a round nut arranged on the withdrawl sleeve, a sieve plate arranged on the upper part of the bearing chamber, an impeller arranged on the main axle and above the sieve plate, an upper spherical-roller bearing arranged on the main axle near to the upper part of the bearing chamber. When the hydrapulper operates, the main axle rotates and the radial positioning of the main axle is realized by the upper spherical-roller bearing and axial fixation action to the main axle together with the spherical-roller bearing is realized, the main axle is prevented from dropping down, the problem that the withdrawl sleeve easily looses is solved, therefore the damag
