    摘要： A ball bearing in which the heat value in an inner ring is decreased and the heat value in an outer ring is brought closer to the heat value in the inner ring by making the radius of curvature for the inner ring groove larger, and defining the radius of curvature for the outer ring groove as 50.5% to 53.0% of the ball diameter. The arrangement of the present invention suppresses the heat value in the entire ball bearing and extends the bearing life at a reduced cost without using a large flow rate lubrication method or a preloading method such as constant preloading. In addition, a decrease in heat generation, seizing resistance and wear resistance can be attained further by optimizing a relation between the raceway groove and the ball diameter, by optimizing the number of balls, by controlling the ingredient composition for the material of the bearing ring, and by forming a hard deposition film on the surface of the raceway groove. Thus, according to the present invention, a ball bearing having a long life is provided even during high speed rotation at a dmn value of 2,000,000 or more.
