[0002] The self-aligning roller bearing has double-row rollers and has self-aligning performance, so it is not easily affected by the angular error between the shaft and the bearing housing seat or the shaft bending. After the self-aligning roller bearing is processed, a measuring device is needed to detect its spherical surface.

[0003] The patent with the application number 202222227634.3 discloses a spherical surface measuring device for a self-aligning roller bearing, which includes a workbench. A number of self-aligning roller bearing bodies are arranged inside the workbench. A clamping plate is arranged on one side of the self-aligning roller bearing body. One side of the clamping plate is hinged with an adjusting plate through a control plate. A moving block is lapped on one side of the adjusting plate. The lower sides of the three moving blocks are fixedly connected to the upper side of the same workbench through three second telescopic rods. The three moving blocks are fixedly connected by two moving bars.
