Abstract: A rolling bearing includes: an inner ring mounted on a shaft to be supported; an outer ring provided around an outer periphery of the inner ring; a plurality of rolling elements rolling while contacting with an inner peripheral face of the outer ring and an outer peripheral face of the inner ring at surfaces thereof; and a retainer supporting the rolling elements. A sliding resistance-reducing film is formed on at least one of a first group being an outer peripheral face of the retainer or the inner peripheral face of the outer ring and a second group being an inner peripheral face of the retainer or the outer peripheral face of the inner ring.

Abstract: When an information provision program is implemented, an input screen is displayed on a display section (step 101). A specific designation number is input (step 103), and one or plural bearing performance indexes are selected (step 107). When bearing performance indexes are selected, bearing service conditions which are required depending on the bearing performance indexes are input. Then, performance calculation programs corresponding to selected bearing performances are activated (steps 110-1, 110-2, . . .), and obtained calculation results are simultaneously displayed.

Abstract translation: 当实现信息提供程序时，在显示部分上显示输入画面（步骤101）。 输入具体的指定号码（步骤103），并选择一个或多个轴承性能指标（步骤107）。 当选择轴承性能指标时，输入根据轴承性能指标要求的轴承维修条件。 然后，激活对应于所选轴承性能的性能计算程序（步骤110-1,110-2 ...），并且同时显示获得的计算结果。

Abstract: In the ball bearing, the ratio of the radius of curvature of an inner race raceway 4 to the outside diameter of balls 8, 8 is set in the range of 0.51 to 0.54. Also, the ratio of the radius of curvature of an outer race raceway 6 to the outside diameter of balls 8, 8 is set in the range of 0.54 to 0.56. Further, an interior geometric clearance c is set at 13 nullm or less. Thanks to these specifications, the balls 8, 8 can be prevented from running up onto the edge of the outer race raceway 6.

Abstract translation: 在球轴承中，内圈滚道4的曲率半径与滚珠8,8的外径的比率设定在0.51〜0.54的范围内。 此外，外圈滚道6的曲率半径与滚珠8,8的外径的比率设定在0.54〜0.56的范围内。 此外，内部几何间隙c设定为13μm以下。 由于这些规格，可以防止滚珠8,8向上跑到外圈滚道6的边缘上。
