Abstract

To increase the load-carrying capacity or rolling capacity of a roll assembly in a rolling mill, throttle elements are used, which shut off the lateral flow of the lubricating film in a partial region between the roll neck and the bearing surface of the roll neck bearing assembly, thereby bringing about an increase in pressure in the lubricating film. At least one throttle element is embodied as an annular segment, forming an angular shut-off region for the lubricant in the annular gap. The invention makes it possible for existing installations to be easily retrofitted, without the need for structural modifications. In the case of new installations, the same load-carrying capacity as before can be provided while the dimensions of the installation space are reduced. The load-carrying capacity of the bearing assembly can be flexibly adjusted based on the dimensions of the shut-off region for the flow of lubricant.
