REPAIR OF WORN-OUT BEARING SYSTEM Russian patent published in 2015 - IPC B21B28/02 F16C13/02 

FIELD: process engineering.

SUBSTANCE: invention relates to reconditioning of rolling mill roll journal bearing system. Bearing system comprises pad with thrust block with journal bush fitted on roll journal in said thrust block and machined by reduction of its first diameter D_a below threshold magnitude D_ak. Note here that simultaneously new thrust block is prepared, its ID D_{i neu} complies with reduced OD of additionally processed journal bush so that clearance in bearing between ID D_{i neu} of new thrust block and OD decreased threshold magnitude of additionally processed journal bush stays in preset permissible range.

EFFECT: longer service life.
