FIELD: machine engineering.
SUBSTANCE: invention relates to a cooled multi-support guide roller (1) for guiding a metal rod (S) in the continuous casting plant. The guide groove roller (1) comprises a collector beam (7) having cantilevers (10, 10a, 10b). Between each two consecutive cantilevers (10, 10a, 10b) there is at least one pipe (11) for cooling liquid for hydraulic connection of said cantilevers (10, 10a, 10b). Each external console (10a) comprises at least one first branch pipe (8) for internal cooling of the cooled guide groove roller (1) and at least one second branch pipe (9) for cooling hubs (4) of the bearings. The first branch pipe (8) is hydraulically connected to the channels (3) of the separate rollers (2 a, 2b). The second branch pipe (9) is hydraulically connected to the hubs (4) of the bearings via the cantilevers (10).
EFFECT: improved strength and reliability.
