Abstract: A roll stand (1) includes a roll (3), in particular a backup roll, mounted via oil film bearings (2). Each oil film bearing (2) has a sealing system for sealing the oil film bearing (2) to prevent oil leakage and a coolant ingress. The oil film bearing (2) is integrated into an oil-circulating lubrication system (4), which is fluidically connected to the oil film bearing (2) via oil feed lines (5) and an oil discharge line (6). A first sensor (11) is arranged in the oil feed line (5) and a second sensor (12) is arranged in the oil discharge line (6). The two sensors (11, 12) are designed to determine the coolant content in the relevant oil volume flow.

Abstract: A seal (100) for sealing a lubricant space prevents lubricant (320) escaping. A rolling stand has a seal of this kind. The seal (100) is made at least partially from elastic material. To enable a pressing force FR, with which the bottom face (112) of the seal is pressed against an opposite contact surface (218), for example of a roll journal (212), to be variably set, the seal (100) has at least two cavities, which are separated from each other in the circumferential direction and which are open towards the lubricant space of the bearing.

Abstract: An oil film bearing includes a journal bush and accommodates a conical roll journal of a backup roll in a rolling mill stand. In order to form a sufficiently large lubricant film gap between the inner side of the journal bush and the outer surface of the roll journal during rolling operation when passing through the angular range with maximum pressure load, and at the same time to prevent the axial forces acting on a fastening ring holding the journal bush on the roll journal in the axial direction from becoming too great, the journal bush to be designed in accordance with the following formula: 0.35
