[0002] Bearings are a crucial component in modern mechanical equipment. Their primary function is to support rotating parts, reduce friction during movement, and ensure rotational accuracy. While bearings are essentially designed to support shafts, this is only part of their function. Support essentially means bearing radial loads and can also be understood as securing the shaft. The floating bearing in a turbocharger is an axially movable bearing designed to allow for thermal expansion of the shaft. Floating bearings require inspection during production, processing, and routine maintenance to ensure reliable quality and prevent breakage during use.

[0003] The existing high-efficiency detection device for floating bearings in floating bearing turbochargers has certain defects. The detection method of the detection device is relatively simple and can only perform detection of a single item. Moreover, the detection device does not have comparative performance during detection, resulting in low accuracy of the detection structure of the detection device, which has a certain impact on the use process. Therefore, improvements are now made to the high-efficiency detection device for floating bearings in turbochargers. Summary of the Invention
