Abstract
For rolling a workpiece with a rolling tool with several rolling elements arranged in hydrostatic bearings, during rolling, only some of the rolling elements engage the workpiece, while the rolling elements not engaging the workpiece essentially seal off the hydrostatic bearing. In such a rolling tool, the rolling elements are arranged so as to be distributed over an area, and each of the hydrostatic bearings includes a circumferential seal in the region of the rolling elements.
