<P>PROBLEM TO BE SOLVED: To provide a rolling bearing and a rolling bearing device capable of suppressing the heat generation of the bearing due to shearing of grease even in business operation after running-in operation. <P>SOLUTION: The rolling bearing has a plurality of rolling bodies between an inner ring and an outer ring and a holder for holding interval of the plurality of rolling bodies in a peripheral direction constant and is characterized in that the quantity of the grease between each of a plurality of rows of rolling bodies in the inner circumferential surface of the outer ring is more in the lower side than in the upper side in a gravity direction when the rolling bearing is assembled in the shaft box. Further, in the rolling bearing device having the rolling bearing and a shaft box for assembling the rolling bearing, the quantity of the grease between each of a plurality of rows of the rolling bodies in the inner circumferential surface of the outer ring is more in the lower side than in the upper side in a gravity direction when the rolling bearing is assembled in the shaft box. <P>COPYRIGHT: (C)2013,JPO&INPIT |
