Abstract
A tubular roll with glide bearings and a method for providing a tubular roll mantle with glide bearings. The roll mantle is supported on a roll axle by hydraulic glide bearing elements which are loaded hydraulically by a pressure medium. The roll is loaded from outside radially in a principal loading direction and the roll mantle is supported on the roll axle by glide bearing elements in the principal loading direction. The loading pressure and lubricant are fed to the glide bearing elements as separated from one another so that the movement of the roll mantle, the speed of movement and the change in speed are regulated by opening, closing and/or throttling the flow in the pressure duct of the loading pressure. The lubricant may be fed to the glide bearing elements irrespective of the loading pressure.
