A press roll with adjustable sag includes a yoke on stationary flexure girder and a hollow roll shell rotatable around the flexure girder. A hydraulic support device disposed between the flexure girder and the roll shell transmits a pressing force from the flexure girder to the roll shell. An outer gear rim which meshes with a drive pinion is fastened to the roll shell. A gear housing which surrounds the gear rim and the drive pinion, is supported by means of support bearings against the roll shell by a centrally arranged support disk thereof and the support bearings are disposed radially within the outer gear rim on both sides of its support disk. On each side of the outer gear rim, the gear housing is provided with a tubular collar piece on the outside of a support bearing.
