[0002] ‌The deep groove ball bearing is the most widely used rolling bearing; its characteristics are small friction resistance, high rotational speed, and can be used on parts that can bear radial loads or combined loads acting radially and axially simultaneously, or can also be used on parts that can bear axial loads. During the production and processing of deep groove ball bearings, detection devices are required to detect their various indicators. However, when the existing detection devices detect the size of bearings, most workers use a scale to measure the inner diameter and outer diameter of the deep groove ball bearings.

Moreover, different-sized bearings cannot be conveniently fixed during the detection process, making the detection function relatively single, thus reducing the detection efficiency of the bearings.
