FIELD: technological processes.
SUBSTANCE: film-lubrication bearing includes bushing-insert, which is installed in the chuck of forming roll, bushing-journal, which is hafted on roll cone neck, and thrust unit. Bushing-journal is retained against slipping on roll neck by means of key installed in keyway, which is provided on internal conical surface of bushing-journal and external conical surface of roll neck so that bridge is formed between keyway and end surface of bushing-journal from the side of thrust unit, at that bridge width makes (0.03...0.09) from minimum diameter of internal conical surface of bushing-journal.
EFFECT: increase of bearings rigidity; rolling accuracy and quality of rolled material.
