A bearing unit of a working element of a soil-cultivating unit contains a body, welded to a post, an axle with a working disk fixed thereto. On the axle on the side, opposite to the disk, a conical bearing for accepting axial loads from the reaction of the soil is mounted, after which a blank cover, and, closer to the working disk, a distance sleeve with a gasket, a carrying ring and a female screw, a plain washer and a lock nut pin to tighten the bearings are arranged. On the axle on the side of the working disk a radial bearing for accepting the radial loads from the reaction of the soil and the weight of the unit and, through a distance collar, an angular-contract bearing, which also accepts radial loads, and, additionally, axial ones from possible overtightening the bearings, while tightening the female screw, are arranged.
