A study published last month in the Chinese defense engineering journal Acta Armamentarii described how researchers have developed an AI-powered “bearing design agent” — capable of autonomously designing rotating bearings in advanced machinery.
The magazine has long served as a leading publishing platform for China’s arms industry, covering technologies related to space, missile systems, armor, guidance systems, and military manufacturing.
Titled “A Study on a Rolling Bearing Design Agent Based on Large Language Models with Thinking and Action,” the paper detailed an artificial intelligence system called ChatBearing that combines large language models, engineering calculation tools, and industrial databases.
Researchers from the State Key Laboratory of Mechanical Transmission of Advanced Equipment at Chongqing University said the system can independently perform design requirements analysis, load calculation, bearing selection, life prediction, strength verification and report generation.
According to the researchers, the design of conventional bearings relies heavily on experienced engineers, long trial-and-error processes, and expensive testing under extreme conditions including high temperatures, heavy load, and high rotation speed.
