BEARING ARRANGEMENT AND ROTARY INLET FOR A COOLED ROLLER

摘要

The invention relates to a bearing arrangement and a rotary inlet for a cooled roller. The aim of the invention is to provide a simple rotary inlet for a cooled roller while maintaining high reliability, such that firstly a seal element has only a small number of individual parts, and secondly a fast exchange of the seal element is possible. Said aim is achieved by means of a device of the type specified in the introduction, in which the coolant pipe (9) is connected to the roller body (4) via at least one sleeve-shaped sealing element (10) with an inner and an outer lateral surface (11,12), wherein the inner lateral surface (11) is sealingly connected to the stationary coolant pipe (9) and the outer lateral surface (12) is sealingly connected to the rotating roller body (4); and the sealing element (10) has at least one, preferably at least two static seal(s) (13) on the outer lateral surface (12) thereof, and has at least one, preferably at least two, dynamic seal(s) (14) on the inner lateral surface (11) thereof.
