<p><P>PROBLEM TO BE SOLVED: To provide a rolling bearing capable of being used even under an extremely cold environment without degrading lubrication performance. <P>SOLUTION: The rolling bearing 1 includes an inner ring 2; an outer ring 3; and a plurality of rolling bodies 4 rollably arranged between the inner ring 2 and the outer ring 3. A lubricant 6 is filled in a bearing space S1 between the inner ring 2 and the outer ring 3. A temperature-raising device 11 for raising the temperature of the lubricant 6 is provided, For example, the temperature-raising device 11 is made to the one in which a ring-like member 13 for covering an outer side in an axial direction of the bearing space is provided and a heater 12 is mounted to an inner surface in an axial direction of the ring-like member 13. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
