According to the "Analysis Report on Production and Sales Demand Forecast and Transformation Upgrading of China's Bearing Manufacturing Industry", the total industrial output value of China's bearing manufacturing industry showed a year-on-year growth trend from 2009 to 2013. In 2013, the industry achieved a total industrial output value of 249.363 billion yuan, a year-on-year increase of 12.92%. Analysis of data from the past five years reveals that the sales revenue of China's bearing manufacturing industry has been increasing year by year from 2009 to 2013. 

In 2013, the sales revenue reached 249.012 billion yuan, a year-on-year increase of 11.80%. The bearing industry in our country is developing rapidly, with the variety of bearings increasing from few to many, product quality and technical level decreasing from low to high, and the industry scale growing from small to large. A professional production system with a basic complete range of product categories and a relatively reasonable production layout has been formed. In 2023, the research team of the Engineering Ceramics Laboratory at the Korea Institute of Materials Science and Technology manufactured silicon nitride bearing balls for electric vehicle drive modules. It is expected that by 2026, the global market size of hybrid bearings using silicon nitride bearing ball technology will grow to over 1.3 trillion Korean won.
