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

The invention relates to a device for strip guidance in a hot medium, comprising a deflection roller () mounted on supporting arms () and a carrier device holding the supporting arms (). The device is characterized in that one of the supporting arms () is mounted on the carrier device by means of a floating bearing (), wherein the floating bearing () allows the mounted supporting arm on the carrier device to move parallel to the longitudinal direction of the deflection roller (), and in that an elastic counter element (), which acts parallel to the longitudinal direction of the deflection roller () upon the supporting arm () mounted on the floating bearing (), is present and counteracts an increasing distance between the supporting arms (). In this way, the technical problems of offsetting a temperature-induced length change of the deflection roller and avoiding an uncontrolled movement of the system are solved.
