Abstract: A bearing closure device has a externally threaded ring that can be slid onto a roll journal. One stop close to the roll barrel and one stop away from the roll barrel are provided on the roll journal in order to limit the axial movement of the threaded ring. A ring nut with an internal thread is screwed onto the external thread of the threaded ring. To facilitate safe screwing on and unscrewing of the ring nut and to keep screws pressure-free during the operation of the bearing a pressure ring is mounted between the bearing and the threaded ring in an axially displaceable manner. In addition, a plurality of screws can be screwed into axial threaded bores in the threaded ring in order to press against the pressure ring in the axial direction. Finally, the ring nut can be screwed or adjusted against the pressure ring.

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.
