Wanxiang Qianchao Ball Screw Bearing Unit for Brake-by-Wire Systems Gains Provincial Project Approval

Wanxiang Qianchao's "Automotive Brake-by-Wire System Ball Screw Bearing Unit" project recently passed review by the Zhejiang Provincial Department of Economy and Information Technology and was successfully included in the 2025 Provincial Industrial New Product Development Project Plan.

Currently, the drive-by-wire chassis has become a golden opportunity for the development of intelligent vehicles. With the continued increase in penetration of key components such as brake-by-wire systems, electronic power steering systems, and electronic parking systems, the market demand and application scale of ball screws are also rapidly expanding. As a key transmission element for bidirectional conversion between rotational and linear motion, ball screw bearings offer significant advantages such as high precision, reversibility, and high efficiency. They are widely used in high-end equipment such as automobiles, humanoid robots, machine tools, automated production lines, and aerospace.

Based on the company's strategic layout in the direction of "intelligent control of mobility", Wanxiang Qianchao seizes the development opportunities brought by the electrification and intelligence of automobiles, seizes the window period for domestic substitution of ball screw bearing units, takes automotive screws as an important breakthrough, and establishes a special R&D team. Using the hard-core technologies of precision universal joints and high-speed ball bearings, it systematically carries out the R&D and industrialization of ball screws for automotive wire control brake systems, striving to break through key technical bottlenecks and overcome "bottleneck" product problems.

This project meets provincial approval requirements in terms of industrial policy, technological advancement, and product innovation. It possesses independent intellectual property rights, boasts a technological level that is at or above the domestic advanced level, and demonstrates positive economic and social benefits and broad market prospects.

Building on this foundation, Wanxiang Qianchao will strengthen R&D investment and technological breakthroughs, achieving systematic innovation and breakthroughs in all aspects of new bearing units in the field of artificial intelligence. This will establish an independent R&D system for ball screw bearings, further promoting industrial innovation and upgrading in Zhejiang Province, and contributing to the localization and independence of bearings.
