Metal sheets having a low deviation of sheet thickness are produced by rolling a sheet through a finishing rolling mill in which at least a final stand is provided with oil film bearings of a rolling roll, each of which consists of a bushing in a roll chock bearing box and a sleeve tightly fitted to a tapered neck of the roll to form a journal relative to the bushing, and is provided with a key connection fixing the sleeve to the rolling roll in a zone of less than 0.2 times the length of a bearing pressure receiving zone from the end of the tapered fitting zone of the sleeve and the roll neck. |
