Deep cooperation with world-class bearing companies SKF and NSK Independently developed household appliance deep groove ball silent bearing cages and engineering machinery, agricultural machinery cone bearings Cages have achieved domestic substitution relatively early Building the earliest intelligent and automated production line in the country

Domestic companies that were among the first to produce wind power pitch bearing cages and wind power gearbox bearing cages. The customer base has expanded to the world's eight major bearing companies. The supplied products have expanded from the initial ball bearing cages to tapered roller bearing cages. The end applications of bearing cage products have extended to fields such as automobiles. Awarded the 'China Machinery Industry Science and Technology Award'. Established the 'Shandong Province Wind Power Bearing Cage Engineering Laboratory' technology innovation platform. Key participation in the formulation of national standards for bearing cages.

Based on the commonality of market customers and technology, leveraging synergy to enter the automotive precision parts industry. First batch to enter NIO's supply chain: supplying components for electric drive systems of new energy vehicles. Entering the supply chain of the top 100 global automotive parts companies: supplying core components for automotive transmission systems, drive systems, and safety systems.
