  • Patent number: 7065876
    Abstract: The invention relates to an extra-roll slide bearing system (20) for a paper/board machine or a finishing machine, surrounding a shaft (2) in a roll (1). The bearing system comprises a body section (5), which is formed with a bearing housing (7) provided with hydrostatic bearing elements (3, 3A) disposed around the shaft (2). The bearing elements are fitted with slide elements (4, 4A), having a sliding surface (16) directed towards the shaft (2). Between the slide elements (4) and the shaft (2) is a bushing (6), which is mounted on the shaft (2) for rotation therewith, said slide elements (4, 4A) being adapted to position themselves around the bushing (6) with the sliding surfaces (16) against the external surface of the bushing directed away from the shaft for supporting said shaft (2), and hence the roll (1), rotatably relative to the body section (5). The bearing housing (7) has its axial ends provided with end caps (8, 9), along with packing elements (12, 14) therefor, for sealing the bearing housing.
