rollings文件内为自制轴承损伤图像，其中dust文件为退役轴承表面锈蚀损伤图像；normal文件为轴承原始图像（未作损伤处理）。采用CCD工业相机Basler acA3800-10gm对6206型退役深沟球轴承端面图像进行采集，AOI区域大小为3840*2748，图像中包含多种损伤类型，为之后进一步研究损伤识别提供数据基础。

The rollings file is the self-made bearing damage image, and the dust file is the surface rust damage image of retired bearing. The normal file is the original bearing image (without damage treatment). CCD industrial camera Basler acA3800-10gm was used to collect the end image of type 6206 retired deep groove ball bearing. The AOI area size was 3840*2748, and the image contained a variety of damage types, which provided data basis for further research on damage identification.
