摘要:
An oil film bearing (1) for roll pins (4), which or whose pin bush (3) that is placed thereon is surrounded by a bearing bush (3) placed in an insert (2). The bearing bush has at least two inner lying hydrostatic pockets (9, 9'), which are arranged, in essence, in a common axial line and which can be supplied with a pressure medium via a check valve (18) and via boreholes (6, 6') extending inside the bearing bush (5). Throttles (15, 15') inside the boreholes (6, 6') ensure an optimal hydrostatic bearing even when the roll pin (4) or the pin bush (3) is in an oblique position inside the bearing bush (5). The aim of the invention is to improve an oil film bearing of the aforementioned type whereby economically assuring the hydrostatic function of the bearing and in which the inspection of the throttles (15, 15') is possible without further ado. To this end, the invention provides that the at least two boreholes (6, 6') are connected to a connection block (12), the throttles (15, 15') are accommodated inside this connection block (12), and the check valve (18) is assigned to said connection block (12).
