In recent years, the bearing company has relied on technological innovation and independent R&D to supply high-end customers both domestically and internationally, gradually replacing imported bearings. In particular, the company’s flagship tapered roller bearings have achieved leading domestic and internationally advanced levels in terms of performance indicators such as service life reliability, rotational torque, vibration, and noise. The company also holds the number one market share in the pickup truck sector.

Guided by the principle of “what users and the market demand,” and within the context of the nation’s “dual-carbon” strategy, our company consistently focuses on enhancing bearing efficiency, reducing manufacturing costs, ensuring high reliability, and adapting to evolving market trends. The Qianchao Bearing Technology Center undertakes internal R&D of foundational technologies and takes on external responsibilities for developing new product projects, leveraging technological innovation to meet emerging market challenges. To date, we have successfully developed several advanced bearing series: a long-life tapered roller bearing series with a lifespan reliability improved by more than eight times; a low-friction-torque tapered roller bearing series that reduces friction torque by over 30%; a low-noise tapered roller bearing series whose vibration (velocity) limits meet the strictest standards; and a high-speed tapered roller bearing series whose maximum allowable speeds have increased by more than 30%. Meanwhile, the Technology Center boasts a range of cutting-edge technologies, including innovative “four-convex” designs for deposited tapered roller bearings, low-friction, high-load-bearing designs, and lightweight cage designs; advanced analysis and prediction techniques such as finite element methods and Romax transmission simulations; specialized production technologies like carbon-nitrogen co-diffusion, salt-bath quenching heat treatment, high-cleanliness manufacturing, and ultra-precision integrated raceway flange finishing; as well as specialized testing technologies—including friction torque tests under specific operating conditions, simulated durability tests, and high-speed endurance tests—that lay a solid foundation for our production processes.

Guided by the design principles of platformization, standardization, serialization, and universality, the tapered roller bearing project team at the bearing company has developed ten single-row tapered roller bearings and three double-row tapered roller bearings that meet the most stringent technical specifications set by OEMs, thereby satisfying the requirements of G Company—a key customer—for its pickup truck platforms. In the course of collaborating with G Company, the project team proactively assisted the customer in analyzing technical solutions during the early stages, systematically arranged and combined different product configurations, and recommended the optimal bearing options. At the initial stage of mass production, company representatives traveled to G Company’s pickup truck production bases in Baoding, Chongqing, and Jingmen to promptly address various zero-kilometer quality issues related to bearing usage, providing customers with the technical solutions they needed and earning a strong reputation. Currently, the bearing company’s tapered roller products account for nearly 80% of the market share in G Company’s pickup trucks.

Last year, the bearing company collaborated with Company J to develop a dual-row tapered roller bearing for wheel hubs. From raw material selection to seal ring fabrication, the entire process was carried out strictly in accordance with Company J’s testing standards. The project team successfully overcame key technical bottlenecks and, in the shortest possible time, ensured that the product passed various tests—including raceway fatigue, transportation simulation, and mud performance—successively. After delivery, all road test samples performed exceptionally well, with zero failures, earning unanimous praise from the customer. This project is expected to boost sales by an additional 20 million yuan.

Next, the bearing company will continue to deepen its presence in the pickup truck market while actively exploring new markets for new-energy reducers, electric drive axles, and maintenance-free wheel hub bearing units for heavy-duty trucks. Focusing on various performance indicators, the company will strengthen its fundamental research, leverage technological innovation to seize market opportunities, and promote its high-quality, sustainable development.
