The invention relates to a strand guide roller 100 of a strand guide device for guiding a cast strand 200. The stand guide roller includes at least one first and one second sectional roller arranged next to each other, wherein the first sectional roller 110-1 has a roller journal 112-1 at its end surface adjacent to the second sectional roller. In addition, the strand guide roller includes a middle bearing 120-1, 120-2 between both sectional rollers 110-1, 110-2 for receiving and supporting the roller journal 112-1 of the first sectional roller. In order to improve strand guidance by increasing the bearing surface for the strand 200, it is suggested, according to the invention, that the first and second sectional rollers be connected with each other outside of the middle bearing by a plug-in connection. Then, according to the invention, the middle bearing is formed simply as unsplit separate bearing with an essentially smaller window width in comparison with a split bearing.
