Abstract

A device for connection of a coolant feed to a roller, especially for continuous casting plants, is arranged in that the roller is mounted by journals in bearing blocks in rolling bearings and is supplied with coolant by way of axial bores through the journals. The device includes a flange with an elastic sleeve that is fixable thereon. A first sealing element has a first sealing surface that is fixable on the elastic sleeve and is rotatable therewith. A second sealing element has a second sealing surface engagable with the first sealing surface and is fixed to, supported by or integrated into a bearing block cover fixed on the bearing block for covering the roller bore and the roller bearings. An axial bore penetrates the elastic sleeve and the bearing block cover and permits feeding of coolant into the interior of the roller. The sealing surfaces of the sealing elements are perpendicular to the rotation axis.
