Ball Screws: Fueled by EV and Renewable Energy Boom, Global Market Sees Steady Expansion with Asia-Pacific as Core Driver

As a critical component enabling precise linear motion, ball screws are experiencing robust demand growth amid the global shift toward electrification and sustainable energy. The latest industry research and enterprise innovations indicate that the global ball screw market is entering a phase of steady expansion, driven primarily by the booming electric vehicle (EV) sector and the widespread adoption of renewable energy technologies. With Asia-Pacific dominating the market share, the industry is also witnessing intense competition and continuous technological breakthroughs focused on efficiency, miniaturization, and intelligence.

Market data reveals the solid growth trajectory of the global ball screw industry. According to a recent report by YHResearch, the global market size of ball screws reached approximately 15.93 billion yuan in 2025, and is expected to maintain stable growth in the coming years, approaching new heights by 2032 . Regionally, the Asia-Pacific region holds the largest market share, accounting for about 61% of the global total, followed by Europe (23%) and North America (15%) . In terms of product types, internal circulation ball screws are the dominant segment, capturing around 65% of the market share, while machine tools and injection molding machines remain the largest downstream application areas, representing 43% of total demand . The concentrated market structure is evident, with the top four core brands—including THK, NSK, Hiwin, and SKF—controlling approximately 47% of the global market .

The rapid development of the electric vehicle industry stands out as a key driver of ball screw demand. As governments worldwide tighten environmental regulations and consumers embrace sustainable transportation, EV production and sales have surged, creating massive needs for high-performance ball screws in critical systems such as electric suspensions, electromechanical brakes, and steering actuators. For instance, NSK recently unveiled its Electric Corner Module Concept, which integrates a ball screw-type electric suspension that directly controls the suspension's extension and compression motions, enabling both active/passive control and energy regeneration . Additionally, the ball screws used in NSK's electromechanical brake systems enhance responsiveness while contributing to system downsizing and weight reduction through component integration . In China, the world's largest EV market, policies such as the "New Energy Vehicle Industry Development Plan (2021-2035)" have further boosted market expansion; it is projected that China's new energy vehicle sales will exceed 6 million units in 2025, driving sustained growth in ball screw applications .

Renewable energy applications have emerged as another major growth engine for the ball screw industry. In wind turbines, solar tracking systems, hydroelectric power plants, and energy storage technologies, ball screws play a pivotal role in delivering precise linear motion for demanding tasks . Leading brands highlight that their ball screws offer significant advantages in renewable energy applications, including clean and quiet electromechanical operation (replacing hydraulic systems), low maintenance requirements, long service life, and high precision—critical for safety-related and sensitive control tasks . These features align with the renewable energy sector's focus on efficiency and sustainability, making ball screws an indispensable component in the global energy transition.

Technological innovation remains a core competitive focus for market players, with ongoing advancements in materials, design, and integration. To meet the rigorous requirements of EV and renewable energy applications—such as high temperature resistance, wear resistance, and miniaturization—manufacturers are adopting high-performance materials like high-strength stainless steel, superalloys, and silicon nitride . Precision machining technologies, including CNC turning and grinding, have improved product accuracy and surface finish, reducing friction coefficients and enhancing transmission efficiency . Moreover, intelligence and integration have become key trends: integrating sensors into ball screws enables real-time monitoring of operating conditions (temperature, speed, load), while AI-driven data analysis facilitates predictive maintenance and lifespan forecasting . Modular design has also gained traction, simplifying installation, maintenance, and integration with other components like motors and reducers .

The global ball screw market features a competitive landscape with a mix of established international giant brands and emerging domestic brands in China. International brands such as THK, NSK, SKF, and Rexroth leverage advanced technology and strong brand recognition to dominate high-end segments, particularly in EVs and large-scale renewable energy equipment . Meanwhile, Chinese brands including AZI, Bot Precision, and Hiwin (Taiwan region) have expanded their market share in the mid-to-high-end segment, capturing nearly 45% of China's domestic market . Supported by national policies like the "Strong Foundation Project" and the "14th Five-Year Plan for Intelligent Manufacturing," Chinese enterprises are making significant progress in core technologies such as high-purity special steel production and bainitic isothermal quenching, gradually increasing the localization rate of high-end ball screws .

Industry experts note that the ball screw sector is poised for continued growth, driven by the deepening of global electrification and the expanding renewable energy market. Future development will focus on three key areas: advancing the localization of high-end products to address potential supply chain bottlenecks, promoting green manufacturing practices (such as adopting recyclable materials and optimizing energy efficiency), and enhancing intelligent features through sensor integration and data analytics . Strengthening industry-university-research collaboration will be crucial to breaking through technical barriers across the entire value chain—from materials and design to manufacturing and testing—enabling domestic brands to compete more effectively on the global stage .

As the world accelerates toward a more sustainable and electrified future, ball screws—with their critical role in precision motion control—are set to maintain their growth momentum. Continuous innovation and expanding application scenarios will drive the industry toward higher quality, efficiency, and sustainability in the years to come.
