Hebei Bearing Industry Technology Research Institute has started the research and development project of aircraft gear box bearings since 2015, and achieved mass production of the product in 2016. The bearing model ZY-N2926M/P2, with wear resistance, long life, high speed, low noise and other characteristics, its product accuracy reached P2 level. The research and development of this product adopts advanced design concept, high-precision processing technology and special manufacturing process. The first batch of products were applied to aircraft gearboxes and showed good performance.

In 2017, the product passed the scientific and technological achievements appraisal of China Bearing Industry Association and obtained the relevant patents. China Bearing Industry Association subsequently recommended the project to apply for the "2019 China Machinery Industry Science and Technology Award", and the product was finally awarded the award because of its outstanding technological innovation and market application value.

Through independent research and development, Shaft Research Institute has not only successfully developed high-performance bearings suitable for aircraft gearboxes, but also achieved mass production and export of products, making important contributions to the technological progress and industrial development in the field of domestic aviation bearings.
