The invention concerns a method for providing a tubular roll mantle with glide bearings. The roll mantle (12) is supported on the roll axle (11) by means of hydraulic glide bearing elements (14, 14a), which are loaded hydraulically by means of a pressure medium. The roll is loaded from outside radially in the principal loading direction (A), and the roll mantle (12) is supported on the roll axle (11) by means of glide bearing elements (14, 14a) in said principal loading direction (A). The loading pressure and the lubricant are fed to said glide bearing elemements (14, 14a) as separated from one another so that the movement of the roll mantle (12), the speed of movement, and the change in the speed are regulated by opening, closing, and/or throttling the flow in the pressure duct (32, 32a) of the loading pressure. The lubricant can be fed to the glide bearing elements (14, 14a) irrespective of the loading pressure. The invention also concerns a roll provided with glide bearings.
