Abstract

A method for cooling a roller device, which has a right bearing housing, a left bearing housing, and a roller, which is rotatably supported by journals in the bearing housings, especially of strand guide rolls, roller table rollers, pinch rolls, support rolls, or driving rolls in continuous casting plants, in which a cooling medium cools the bearings mounted in the bearing housings and passes through an axial bore in the roller. The cooling medium enters the bearing housing of the roller device on one side, passes around the bearing mounted in this bearing housing, then flows through the axial bore in the roller to the other side, passes around the bearing mounted in the other bearing housing, and is then discharged from the roller device.
