Abstract
A rolling bearing fully-filled with plastic oil comprises an outer ring, an inner ring, a rolling element between the outer ring raceway and the inner ring raceway, a cage, and a plastic oil to provide lubrication for the bearing. The plastic oil includes a porous lubricating material containing oil. The plastic oil in a fluid state is combined with the rolling element and the cage to present a plastic state and forms an assembly of the rolling element, the cage and the plastic oil after the plastic oil is heated and cured with the bearing. When the bearing is running, the assembly revolves, the rolling element rotates in a window or pocket of the cage, and the lubricating oil contained in micropores of the plastic oil spills out of the micropores to lubricate the bearing.
