Abstract
The invention relates to a rotary lead-through for the coolant inflow and outflow of a back-up and/or conveyor roller () which is held in a bearing arrangement at the end at least by means of bearing journals () located in bearing blocks (), 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 () 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 () and a covering plate (), wherein a fixed sleeve (), sealed in the bearing journal (), is sealed at the covering plate () by means of a rotary shaft sealing ring () which makes it possible for relative rotary movement and oscillating movement to occur.
