<p>PROBLEM TO BE SOLVED: To provide a rolling bearing device which can suppress uneven distribution of a lubricant inside the bearing and prevent failure of the bearing part due to poor lubrication.SOLUTION: A rolling bearing device 1 comprises: an outer ring 2 in whose inner periphery an outer ring raceway 2a is formed; an inner ring member 3 in whose outer periphery an inner ring raceway 3a is formed; a plurality of rolling elements 4 which roll between the outer ring raceway 2a and the inner ring raceway 3a; a retainer 5 which retains the plurality of rolling elements 4; and a sealing device 6 which is fitted into an inner periphery 2d at an axial end of the outer ring 2 and slidably contacts the inner ring member 3 to seal an internal space 10 between the inner periphery of the outer ring 2 and the outer periphery of the inner ring member 3. A lubricant 30 is enclosed in the internal space 10. The rolling bearing device 1 comprises: a shield 7 which is fixed to the inner ring 3 and arranged on the rolling element 4 side relative to the sealing device 6; and an oil receiving portion 2d which extends to the rolling element 4 side in an outer periphery of the shield 7.</p> |
