Bearing suspension for twin core sampler unit has hollow shaft, the upper part of this one is arranged with possibility of connection to the body of the saddle of the discharge ball valve. With the outer surface the hollow shaft is connected to the first rings of the bearings, the first of those is made radial; the second rings of the bearings are connected to the body. The body is connected to the core sampler pipe connected to the first elastic ring made of antifriction material, this is placed in the circular reboring of the fixation nut of the first ring of the bearings and closes from beneath the cavity with the bearings filled with plastic oil, this is at above covered with the other similar elastic ring. To decrease probability of shaking and destruction of the core sample the second bearing is made radial or radial-support, additionally a protective unit is provided, this has a circular inner lug of the upper part of the body and the circular outer lug of the hollow shaft, projections of those to the horizontal plane normal to the axis of the bearing suspension overlap not less than by 1.5 mm at the edge of those. The suspension has a profiled elastic ring made of antifriction material placed between the bottom of the inner lug and the upper side of the outer lug, its inner part has cylindrical extension placed in the gap between the hollow shaft and the body.
