摘要： The invention relates to a rotary lead-through for the coolant inflow and outflow of a back-up and/or conveyor roller ( 1 ) which is held in a bearing arrangement at the end at least by means of bearing journals ( 10 ) located in bearing blocks ( 11 ), in particular in a continuous casting plant. To compensate for the axial movement and oscillating movement of the back-up and/or conveyor roller during operation, the bearing ( 9 ) at one end, to which the coolant inflow line and the coolant outflow line is connected, is a fixed axial bearing which is nevertheless able to absorb oscillating movement, while the other bearing is a detached axial bearing. In this way it is possible to provide on the fixed axial bearing a rotary lead-through, without a compensator, between the bearing journal ( 10 ) and a covering plate ( 12 ), wherein a fixed sleeve ( 16 ), sealed in the bearing journal ( 10 ), is sealed at the covering plate ( 12 ) by means of a rotary shaft sealing ring ( 18 ) which makes it possible for relative rotary movement and oscillating movement to occur.

摘要： The invention concerns a roller-equipped guide segment in a continuous casting facility. At least a certain number of rollers are distributed in three axially aligned roller bodies (4a, 5, 6) with the purpose of absorbing as much mechanical load as possible for receiving the supporting force. Only the external roller bodies (4, 6) are axially fixed by means of their external bearings, which are configured in the form of fixed bearings. The central roller body (5) is float mounted. All inner bearings (4b, 6a) of the external roller bodies (4, 6), which are configured as movable bearings, and both bearings (8b, 9a) of the central roller body are configured in the form of high load capacity movable bearings, especially in the form of CARB bearings. The free axial of the float mounted central roller body (5) is limited by stops (11, 12a, 12b, 13) that are configured as stop disks and mounted between the opposite front faces of the central roller body (5) and the external roller body (4, 6).
