Sag (deflection) compensation roll and process for operating sag compensation roll. The sag compensation roll includes a rotatable roll jacket, a non-rotating carrier being located inside the roll jacket, and a hydraulic support element arrangement being located between the carrier and the roll jacket. A bearing ring is located at each end of the roll jacket, the bearing rings are movable relative to the carrier in a press plane, and a bearing arrangement is located between the bearing rings and the roll jacket. The bearing arrangement includes at least three support elements distributed in a circumferential direction. At least one of the at least three support elements is movable with respect to the bearing ring. The process includes supplying the bearing pockets with a constant volume flow of hydraulic fluid, and driving at least one support element into the bearing ring under load up to the fixed position.
