LUBRICATION MECHANISM FOR OUTER RACE ROTATION TYPE BACK-UP ROLL BEARING ROTATABLY ATTACHED ON ROTARY SHAFT

摘要

PROBLEM TO BE SOLVED: To provide a lubrication mechanism for an outer race rotation type back-up roll bearing rotatably attached on a rotary shaft, which can realize a high lubricating property without leaking lubricant outside.

SOLUTION: Respective bearing parts of a plurality of split backup rolls 50, which are connected on a roll support shaft 51 formed of one shaft, are lubricated by oil-air lubrication through rotary joints 90a, 90b.
