Extra-roll slide bearing system for a paper/board machine or a finishing machine

The invention relates to an extra-roll slide bearing system for a paper/board machine or a finishing machine, surrounding a shaft in a roll. The bearing system comprises a body section, which is formed with a bearing housing provided with hydrostatic bearing elements (A) disposed around the shaft. The bearing elements are fitted with slide elements (A), having a sliding surface directed towards the shaft. Between the slide elements and the shaft is a bushing, which is mounted on the shaft for rotation therewith, said slide elements (A) being adapted to position themselves around the bushing with the sliding surfaces against the external surface of the bushing directed away from the shaft for supporting said shaft, and hence the roll, rotatably relative to the body section. The bearing housing has its axial ends provided with end caps, along with packing elements therefor, for sealing the bearing housing. The slide bearing system of the invention is assembled for a single package, which is mountable on the shaft and dismountable from the shaft as a single package.
