PROBLEM TO BE SOLVED: To provide a rolling bearing which enables circulation performance of grease inside the bearing to be improved.SOLUTION: There is provided a rolling bearing 1 in which: a plurality of rolling elements 4 are disposed in an annular space between an outer ring 3 and an inner ring 2 while the rolling elements 4 are held by a cage 5 at prescribed intervals along the circumferential direction; a shoulder diameter at one axial direction-end side of the inner ring 2 is different from a shoulder diameter at the other axial direction-end side of the inner ring; and shielding parts 6 for suppressing leakage of grease in the annular space to the outside, are provided in both axial ends of the annular space. A first clearance c1 between an outer ring inner circumferential surface opposed to a large end side 2b having the larger shoulder diameter of the inner ring 2 and a cage outer circumferential surface opposed to the outer ring inner circumferential surface, is larger than a second clearance c2 between an outer ring inner circumferential surface opposed to a small end side 2a having the smaller shoulder diameter of the inner ring 2 and the cage outer circumferential surface opposed to the outer ring inner circumferential surface.SELECTED DRAWING: Figure 1 |
