FIELD: machine building.
SUBSTANCE: invention refers to hydrostatic bearings for rollers of rolling mill, particularly to structure of mechanical fixation used in connection with pistons-cylinders assemblies equipped with hydraulic drive and implemented for installation of hydro-static bearings on rollers of rolling mill. Hydro-static bearing (B) for the roller of the rolling mill with conic neck (10) transforming into cylinder shank end (12) consists of bushing (18), piston (26), cylinder (28), fixing brackets and lock-nut (58). Bearing (B) is mounted on neck (10) on a roller by means of a module with piston/cylinder (26/28) equipped with a hydraulic drive. The module with piston/cylinder (26, 28) is limited in axial direction with fixing brackets with external thread; also the brackets are installed in circular groove (14) in neck (10). Locknut (58) is screwed along thread on fixing brackets.
EFFECT: improved design of mechanical fixation facilitating reliable installation of hydrostatic bearing whereat bearing is reliably secured in mounting position on necks of rollers.
