Products and R&D
Relying on a state-level enterprise technology center, a state-level postdoctoral research workstation, a CNAS-accredited laboratory, and more than 3,800 accumulated patent technologies, our products from high-speed bearings for passenger vehicle electric drive, chassis core components for commercial vehicles, and electronic control products, to bearings for the low-altitude economy, high-precision bearings for humanoid robots, and transmission modules, we have built a full-chain technology system covering independent design, intelligent manufacturing and testing.

Innovative concept


Guided by the mission of “Making Air Fresher,” and upholding the Tech Qianchao vision of “Innovative Development, Industry Leadership, Green Sustainability, and Global-Local Integration,” we remain firmly committed to a globalization strategy and a digital-and-intelligence-driven operational approach. We have made breakthroughs and achieved new milestones in areas such as reaching out to high-end customers, tackling key technological challenges for new products, and driving digital and intelligent transformation. With bearings and chassis as our “dual core strengths,” we continue to deepen our expertise in the field of intelligent motion control for the machinery industry, positioning ourselves as a global benchmark in the automotive components sector.
