A support arrangement is provided for a variable-crown having a non-revolving roll axle (11) on which the roll mantle (12) revolves. The roll mantle (12) is supported on the roll axle (11) by means of hydraulic loading members (20) which comprise pistons (21) fitted into cylinder bores (15) formed in the roll axle (11), as well as glide shoes (22) supported on the inner face (14) of the roll mantle. The pistons (21) are composed of bushing provided with inside cavity spaces (23). The glide shoes (22) are attached to the outer ends of the pistons through the cavity spaces (23) from outside the bushing, are hydraulically sealed (30), and are pivotal and displaceable in the radial direction of the roll (10). A hydraulic pressure medium is passed into the cavity spaces (23) in the pistons (21) so as to act upon the interior of the glide shoes (22). The hydraulic medium passes via the cavity spaces (23), through capillary bores (28,28') into pockets (31), the latter acting as hydrostatic lubrication spaces of the glide shoes (22).
