<p><P>PROBLEM TO BE SOLVED: To provide a rolling bearing device capable of efficiently supplying lubricating oil between the guide surface of the inner peripheral face of an outer ring and a guided surface of the outer peripheral face of a cage. <P>SOLUTION: The rolling bearing device includes the outer ring 11 at the fixed side, an inner ring 12 at the rotary side, a plurality of balls 13 rollingly arranged between the inner ring 12 and the outer ring 11, and the cage 14 for holding peripheral spaces between the balls 13. The cage 14 has the guided surface 21a guided by the guiding surface 11b formed at the inner periphery of the outer ring 11. An outside spacer 15 is provided adjacent to the outer ring 11. The outside spacer 15 has a grease supply passage 32 formed in a guide clearance S1 between the cage 14 and the outer ring 11 for discharging oil air. The inner ring 12 has an integrally rotatable annular member 40 which forms an oil air distribution clearance S2 between the inner peripheral face of the outer ring 11 and itself. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
