More Information
Summary:The invention relates to a bearing arrangement (5) for a rotatable roll (2) which can be moved in the direction of its rotational axis (R) by vibration excitation and which is mounted at both sides on a machine frame (3) by means of in each case one bearing arrangement (5.1, 5.2) comprising at least one radial plain bearing, in particular a breast roll (2*) in a machine (40) for producing material webs. The solution according to the invention is characterized in that the radial plain bearing of a bearing arrangement (5.1, 5.2) is designed as a hydrodynamic radial plain bearing (6.1, 6.2). The invention also relates to a method for operating a roll (2, 2') which is mounted in this way.
