The invention relates to a rotating, disc-shaped, agricultural tool which is mounted in a frame of a machine via a hub and a bearing arrangement. The bearing arrangement is distinguished by the fact that it is formed from two angular roller bearings which are set in back-to-back arrangement and whose raceways are arranged inclined at an angle to a bearing axis, wherein a space accommodation the angular roller bearings is defined on the outside in the radial direction by a hub body, of V-shaped design in its centre part and having contact surfaces, and on the inside in the radial direction by a supporting ring having spaced-apart contact surfaces on both sides in the axial direction, wherein the hub body is provided at an axial end with a fastening element for fastening the tool. In this way, a captive bearing unit is provided which is already provided with the appropriate prestress and which only needs to be connected to the agricultural tool and to the frame by the end user, i.e. by the manufacturer of an agricultural machine. |
