[0002] Sliding bearing is a mechanical part that uses the friction between sliding contact surfaces to support rotating shafts or reciprocating shafts. Sliding bearings are usually composed of sleeves and bearing shells. The sleeves are fixed on the shafts, while the bearing shells are installed in the bearing seats. During operation, a layer of lubricating oil film is formed between the shafts and the bearing shells to reduce friction and wear, improve load-bearing capacity and service life. Sliding bearings are widely used in various mechanical equipment, such as automobile engines, water pumps, compressors, etc.

[0003] In the prior art, during the production and processing of sliding bearings, the diameter needs to be measured. Traditional measuring devices often use contact measuring tools, such as calipers or micrometers. Although these tools can provide accurate measurement results, the operation process is cumbersome and it is easy to cause scratches or damage to the surface of the sliding bearing. In addition, for mass production, manual measurement is inefficient and it is difficult to meet the requirements of modern manufacturing industry for production efficiency and automation level.
