Claim:
1. A guide roller for guiding a strand in a strand casting system configured to be mounted rotatably in a bearing mount and connected to a coolant supply line, the guide roller comprising: a roller core; a roller jacket disposed around the roller core, a coolant channel being defined between the roller core and the roller jacket; a respective bearing journal situated on each side of the roller core, at least one of the bearing journals being hollow and consisting of a single through hole through which coolant flows when flowing through the bearing journal, the single through hole of the at least one of the bearing journals having an opening that leads into a respective interior space of the roller core, the roller core including at least one radial connecting channel having an opening in flow communication with the interior space of the roller core and another opening in flow communication with the coolant channel such that coolant operatively flows through the at least one radial connecting channel when flowing between the coolant channel and the single through hole of the at least one of the bearing journals; and at least one bearing situated radially outward of each of the bearing journals and configured to enable rotation of the roller core and the roller jacket relative to the bearing mount, and wherein the at least one bearing includes a plain bearing that surrounds the respective one of the bearing journals such that each of the bearing journals is surrounded by a respective plain bearing, and wherein the plain bearing is disposed in the roller core, and wherein the at least one radial connecting channel has dimensions such that the at least one radial connecting channel has a portion that surrounds the plain bearing to enable coolant to flow between the plain bearing and the roller core so that at least one of lubrication, cooling and flushing of the plain bearing is provided.
