<p>A grease-packed rolling bearing for outer-ring rotation is provided. This rolling bearing, which is used in the outer-ring rotation mode, can be rated excellent in all of the prolongation of lubricating grease life, the inhibition of abnormal noise generation at low temperatures, and the prevention of grease leakage. The grease-packed rolling bearing for outer-ring rotation comprises a rolling bearing (A) to be used in the outer-ring rotation mode, such as a pulley bearing, and a lubricating grease (G) obtained by thickening a lube base oil having a dynamic viscosity at 40°C of 13-73 cSt with a urea compound thickener, the grease (G) having been enclosed in the rolling bearing (A) in a volume proportion which is not lower than 20% of the total space volume in the bearing and not higher than 80% of the resting space volume therein.</p> |
