摘要： An inspection method of a rolling element includes the steps of: projecting an X-ray from a light source to a rolling element, detecting the X-ray passing through the rolling element by a detector, calculating data of the detected X-ray to form an image, and detecting a defect in the rolling element based on the image. At the step of projecting an X-ray, the light source rotates relatively around the rolling element while the X-ray is projected to an entire region of the rolling element facing the light source. At the step of forming an image, data of the X-ray for one circuit around the rolling element is calculated to generate the image.

摘要： A spherical body polishing apparatus capable of reducing polishing costs includes a rotating disk having a rotating disk polishing surface and a fixed disk having a fixed disk polishing surface opposed to the rotating disk polishing surface. The rotating disk polishing surface is capable of relative rotation while keeping being opposed to the fixed disk polishing surface. The rotating disk polishing surface has a groove portion formed therein and extending circumferentially along the rotation. The rotating disk having the groove portion therein includes an abrasive grain layer having a higher hardness than that of a material ball which is a spherical body and a holding layer formed on the abrasive grain layer and having a lower hardness than that of the abrasive grain layer. The groove portion is formed to penetrate the holding layer in a depth direction and to reach the abrasive grain layer.

摘要： Impregnation of a resin into a sintered body (15) enables reduction in an amount of oil to be impregnated into inner pores. Further, by forming pores into which the resin is unimpregnated in a bearing surface (inner peripheral surface (15a)), it is possible to supply oil retained in the pores into bearing gaps and to cause the pores to function as filters for catching contaminants such as abrasion powder in a bearing.
摘要翻译：将树脂浸渍到烧结体（15）中能够减少要浸渍到内孔中的油量。此外，通过在支承面（内周面（15a））中形成树脂未浸渍的孔，可以将保留在孔中的油供给到轴承间隙中，并使孔作为过滤器起到捕获污染物的作用作为轴承中的磨损粉末。
