Abstract
A device is described for heat-treating sheet metal strips (6), comprising at least one radiant tube unit (1) which has three tubes disposed in a common plane parallel to the sheet metal strip (6), namely a middle tube (2) that can be connected to a burner and two outer tubes (3) that are connected at both ends to the middle tube (2) by means of tube bends (4), and a bearing (8) on the side of the radiant tube unit (1) opposite the burner for a bearing journal (9) connected to the two tube bends (4) between the middle tube (2) on the one hand and the two outer tubes (3) on the other hand, the bearing journal engaging in a journal receptacle (10) of the bearing (8) in an axially displaceable manner. In order to provide advantageous constructional conditions it is proposed that an insert (16) forming a sliding layer (15) is provided in the support area of the bearing journal (9) between the journal receptacle (10) of the bearing (8) and the bearing journal (9).
