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. The slide bearing system (20) of the invention is assembled for a
single package, which is mountable on the shaft (2) and dismountable from
the shaft (2) as a single package.
