Abstract

PURPOSE: To facilitate repolishing of an outer ring with a high accuracy without disassembling a bearing by spreading the sleeve installed on the outer periphery of an arbour and allowing the outer ring to revolve in the fixed state of an inner ring.
CONSTITUTION: The pressurized oil chamber 24 having the length enough to fix an inner ring 15 by feeding of presurized oil is formed between the outer peripheral surface of an arbour 20 and the inner peripheral surface of a sleeve 23. In order to repolish the outer ring 12, pressrized oil is supplied into the sleeve 23, so as to expand the sleeve 23, and the inner ring 15 is fixed on the arbour 20. After fixation of the arbour 20, the lathe dog 43 of the work head 42 of a polishing machine is inserted into the engaging hole 44 on the bearing outer ring 12 and the outer ring 12 is engaged to permit revolution in intergral form with the head 42 without revolving the inner ring 15.
