Abstract

The invention relates to a device for strip guidance in a hot medium, comprising a deflection roller (3, 38) which has two roller pins (23, 39) and is mounted to supporting arms (1, 2, 34, 37, 54, 57) by means of ceramic journal bearings (20, 31), wherein the journal bearings (20, 31) are in each case arranged in a bearing receptacle (45, 55) of the associated supporting arm (1, 2, 34, 37, 54, 57). The invention is characterized in that at least one of the journal bearings (20, 31) in its associated supporting arm (1, 2, 34, 37, 54, 57) is fixed in the bearing receptacle (45, 55) by means of a force-fit that engages on the outer edge of the journal bearing (20, 31) and balances the different heat expansion coefficients of the journal bearings (20, 31) and the bearing receptacle (45, 55).
