[0002] A bearing housing is a component that supports a bearing to ensure the stability of the shaft during rotation. Bearing housings are generally fixed with bolts, and the bearing is placed inside them. In order to ensure the stability of the bearing and the drive shaft during operation, the inner hole of the bearing housing requires high precision.

[0035] Specifically, limit plates 13 are provided on both sides of the top of the substrate 1. The two ends of the measuring ruler 8 are slidably disposed inside the groove formed by the limit plates 13 and the substrate 1. The measuring ruler 8 can slide inside the groove to adjust the position of the measuring ruler 8.
[0036] In this embodiment, a bearing mounting seat 2 to be tested is provided on the top of the substrate 1;
[0037] In this embodiment, a detection element 3 is inserted inside the bearing mounting base 2. The detection element 3 is used at least for detecting the inner diameter of the bearing mounting base 2.
