FIELD: process engineering.
SUBSTANCE: invention relates to metallurgy, particularly, to mill backup roll bearings. Proposed bearing comprises sleeve-journal mounted at forming roll pin taper section, sleeve-insert arranged between shaft pad and sleeve-journal, thrust bearing and annular hydraulic piston-cylinder unit composed of moving part and fixed part locked at roll pin cylindrical section whereat sleeve-journal may displace due to rigid coupling between moving part of annular unit and sleeve-journal or single-piece design.
EFFECT: longer life.
