A method for compensation of load produced defections in a roll and a roll in which the method is applied. The roll comprises a supporting, non-rotating shaft (1) and a rotatable mantle portion (2) supported thereon by means of a plurality of bearing units (3a, 3b). The bearing units (3a) at the end portions of the shaft (1) are provided with a flexible mounting (6, 8, 9) with respect to the shaft (1) and/or the mantle portion (2). The flexible mounting (6, 8, 9) is connected to flexible elements (4) influencing the support of the mantle portion (2). The spring modulus of the flexible elements (4) is adapted to the stiffness of the shaft (1), so that, under external loading of the roll, the flexible elements (4) allow the ends of said shaft (1) to move radially relative to said mantle portion (2), but resist this movement with an elastic force being dependent on the angle of deflection of said shaft (1 ), thereby keeping the deflection of said mantle portion (2) within predetermined limits.
