Pressure roll having a stationary axial supporting member and having a roll shell rotatable about the supporting member, the said shell being supported by hydrostatic supporting elements; the roll shell is mounted to be mobile in all radial directions relatively to the supporting member, and is guided radially relatively to the supporting member only by means of the supporting elements and by means of at least one counter-roll appointed to the roll shell; the supporting elements are constructed to follow the radial movements of the roll shell.

A roll unit including a. a pressure equalization roll and at least one counter-roll which coacts with the equalization roll to define a press gap, b. the equalization roll comprising a stationary axial supporting member, a series of hydrostatic supporting elements mounted in the supporting member and arranged in a row which extends along the press gap, and a shell which rotates about the supporting member and is supported thereon via the hydrostatic supporting elements, c. the shell being free to move in all radial directions relatively to the supporting member, and the supporting elements being radially displaceable so that they follow radial movements of the shell, d. the equalization roll also including at least one guide ring which surrounds the supporting member and is interposed between that member and the shell, said ring containing a central aperture dimensioned to permit the ring to move in all radial directions relatively to the supporting member; e. means restraining the guide ring against axial movement relatively to the supporting member; and f. means restraining the guide ring against both radial and axial movement relatively to the shell, g. whereby the shell is guided radially solely by the supporting elements and the counter-roll, and is guided axially by the supporting member via the guide ring.
