Also, a grease for rolling bearings is proposed which is less likely to scatter under centrifugal force at high speed rotation, whereby preventing malfunction and noise of electronic information devices. A lubricating oil film of an ester-series oil having a dynamic viscosity at 40° C. of 35 mm2/s or over is formed on the friction surface of a rolling bearing. There is also provided a high-speed rolling bearing in which a lubricating grease having its worked penetration (JIS K2220) adjusted to 175-250 is retained therein. The grease is preferably prepared by adding a thickening agent containing 50 wt % or more of an aliphatic lithium salt 12-24 in carbon number to a base oil comprising 30 wt % or more of an ester oil having a dynamic viscosity at 40° C. of 10 mm2/s or over, and having its worked penetration (JIS K2220) adjusted to 175-250.

摘要： The sectional shape of a rolling surface of at least one of bearing component parts has the following relation between the order n (n being an arbitrarily chosen natural number) and the amplitude r of waviness relative to the circularity of the sectional shape. The order n and the amplitude r are logarithmically transformed to define X=Log(n) from the order n and Y=Log (rn) from the amplitude r of n-order. When a regression line Y=aX+b is determined, the ratio δ/σ of the deviation δ at each X from the regression line of Y to the standard deviation σ is chosen to be smaller than 4.
