The invention relates to a hydrostatic bearing for rotatable bearing of a drum, e.g. a barking drum. The bearing has a bearing box with arcuate edges adapted to the bearing surface of the drum, with a fluid inlet opening inside the edges. In grooves in the edges, sealing strips are movably laid in such a manner that the strips are pressed by the fluid pressure in the bearing box against the bearing surface of the drum when the drum is lifted by the fluid pressure.
