摘要

A roll stand for rolling metallic strips includes at least one roll or cylinder which is respectively mounted in a mounting on rolling bearings in the region of its end journals, and at least one distributing device for distributing a lubricant-gas flow. The roll stand according to the invention makes it easily possible in an operationally reliable manner to supply a rolling bearing, provided for mounting a roll or cylinder, with a precisely determined amount of lubricant. This is achieved according to the invention in that a connecting channel for the transport of a lubricant-gas flow to or from the distributing device is molded into the roll or cylinder.
