“End-face Drive” Leads to Efficient Transmission—Wanxiang Jinggong Once Again Receives the “Zhejiang Manufacturing Excellence” Award
2025-08-13
Recently, the Zhejiang Provincial Department of Economy and Information Technology released the list of “Zhejiang Manufacturing Excellence” products for 2025. The “end-face-driven low-torque hub bearing unit,” developed and designed by Zhejiang Wanxiang Precision Engineering Co., Ltd., is another “Zhejiang Manufacturing Excellence” product following the “low-friction new-type hub bearing unit.”

The end-face-driven low-torque hub bearing unit is a core component of the automotive chassis drive system. It is installed at the vehicle’s wheel axle to support the vehicle’s weight and provide precise guidance for the rotation of the wheel hub. The manufacturing precision, technical performance, service life, and reliability of this component play a critical role in the vehicle’s power transmission, driving performance, braking, and steering.
The end-face spline drive technology is an innovative solution in the wheel hub bearing industry. This technology precisely cold-forms splines and arranges them on the flange’s swaged and flared end face of the wheel hub bearing, enabling radial engagement with the end-face teeth on the drive shaft. During operation, the spline interface of the bearing virtually eliminates any clearance. Compared to conventional products in the industry, traditional internal spline connections may produce abnormal noises due to issues such as insufficient mating precision. By breaking through the conventional connection method between the bearing and the drive shaft, the end-face spline drive technology significantly reduces energy loss, making torque transmission between the wheel hub and the bearing more efficient and stable. As a result, this technology enhances the wheel hub bearing’s torque transmission capacity, the vehicle’s driving torque, and the overall dynamic performance of the automobile.
The performance of the end-face-driven low-torque hub bearing unit brings numerous advantages to vehicle development. This innovative hub bearing has a positive impact on fuel consumption, emissions, performance, drivability, service life, and cost. The product demonstrates significant potential in both current and future markets and represents the industry’s future development direction.
