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).

The invention claimed is: 1. Oil film bearing (1) for roll necks (4), which is surrounded or whose neck bush (3) mounted thereon is surrounded by a bearing bush (5) mounted in a chock (2), wherein the bearing bush (5) has at least two internal hydrostatic pockets (9, 9'), which are arranged essenti
The invention claimed is: 1. Oil film bearing (1) for roll necks (4), which is surrounded or whose neck bush (3) mounted thereon is surrounded by a bearing bush (5) mounted in a chock (2), wherein the bearing bush (5) has at least two internal hydrostatic pockets (9, 9'), which are arranged essentially on a common axial line and can be supplied with a pressure medium via a check valve (18) and via two or more bores (6, 6') that run inside the bearing bush (5), and wherein throttles (15, 15') ensure an optimum hydrostatic bearing, even when the roll neck (4) or the neck bush (3) is in a skewed position in the bearing bush (5), wherein the two or more bores (6, 6') are connected with a connection block (12), the throttles (15, 15') are accommodated inside the connection block (12), and the check valve (18) is assigned to the connection block (12). 2. Oil film bearing in accordance with Claim 1, wherein the connection block (12) is mounted on the chock (2) in such a way that it is freely accessible. 3. Oil film bearing in accordance with claim 1, wherein the bores (6, 6') and the connection block (12) are provided with high-pressure connections (10, 10'; 13, 13') and that the high-pressure connections (10, 10') of the bores (6, 6') are connected with the high-pressure connections (13, 13') of the connection block (12) by rigid lines (11, 11') 4. Oil film bearing in accordance with Claim 3, wherein the lines (11, 11') consist of tubes that withstand pressures above 2,000bars and are elastically deformable to compensate possible relative movement between the bearing bush (5) and the chock (2). 5. Oil film bearing in accordance with claim 1, wherein the check valve (18) and/or the throttles (15, 15') are replaceably assigned to the connection block (12). 6. Oil film bearing in accordance with claim 1, wherein the bearing bush is a bearing bush (5) without a shoulder.
