Rotating method

Abstract

The invention relates to a rotatable lead-through for connection of a coolant feed to a roller, especially for continuous casting plants, which roller is mounted by way of journals in bearing blocks in rolling bearings and which is supplied with the coolant by way of axial bores through the journals, said rotatable lead-through having a flange with an elastic sleeve pressure-tightly fixed thereon, a first sealing element fixed on said elastic sleeve and rotating therewith and having a first sealing surface, a second sealing element having a second sealing surface running on said first sealing surface and being supported by or integrated into a bearing block cover fixed on the bearing block for covering the roller bore and the roller bearings, and an axial bore penetrating said elastic sleeve and said bearing block cover and permitting the feeding of coolant into the interior of the roller, wherein the sealing surfaces of the sealing elements are perpendicular to the rotation axis.
