Abstract

The invention relates to a glide bearing for a roll. The glide bearing comprises several hydrostatic bearing elements (10, 20, 30, 40) which are provided with bearing shoes (16, 26, 36, 41) fitted to be positioned around the neck of a roll (1) axle (3) in order to support said axle (3) and, thus, the roll (1) revolvingly with respect to a frame member, such as a bearing block (4). The bearing elements (10, 20, 30, 40) are hydraulically operating piston-cylinder devices which can be loaded by means of a pressure medium so that the bearing shoes (16, 26, 36, 41) of the bearing elements are able to be positioned freely around the neck of the axle (3). One preferred application of the glide bearing in accordance with the invention is rolls in which at least in the principal loading direction of the roll, in particular in the case of a nip roll in the direction of a nip plane (A-A), the roll (1) can be displaced by means of bearing elements (10, 20, 30), especially for the purpose of closing and opening the nip (N).
