FIELD: machine building.
SUBSTANCE: invention refers to metallurgy and can be used to direct and support a product being cast or rolled. A roller (1) has a cylindrical body (4) with a central channel (5) for cooling medium. A support comprises at least one bearing (6) with outer cover (7) and a bracket (2). A pipe (9) for cooling medium is connected to the roller body (4) via a sealing element (10). The inner side surface (11) of the element (10) is connected to the stationary pipe (9) for cooling medium, and the outer side surface (12) is connected to the rotating roller body (4). The outer side surface (12) of the sealing element (10) is fitted by at least one static seal (13), and the inner side surface (11) - by at least one dynamic seal (14).
EFFECT: higher reliability of support and provision for fast replacement of a sealing element.
