PROBLEM TO BE SOLVED: To provide a long-life rolling bearing by making a moderate amount of lubricant flow into a contact part to suppress initial heat generation and abrasion.SOLUTION: In a rolling bearing, a plurality of rolling elements are rollably held between inner and outer rings, and a grease composition, which apparent viscosity at a shear rate of 0.1 sis in the range of 124-2,340 Pa s, is encapsulated to occupy 15-50 vol.% of a space volume.SELECTED DRAWING: Figure 1 |
