Summary of the Screw Rod Industry Conference Call Industry Overview - The screw rod market is experiencing exponential growth driven by the development of humanoid robots and embodied intelligence, with domestic manufacturers like Zhaowei Electromechanical and Yingshi adopting micro screw rod solutions, significantly increasing demand, especially in the micro screw rod sector [2][3][14] Market Size and Segmentation - The Chinese four-cylinder market (excluding humanoid robots) is approximately 3 billion yuan, with the ball screw rod segment holding the highest share (1.663 billion yuan), while trapezoidal screw rods have the largest sales volume but lower value (1.064 billion yuan), and planetary roller screw rods have the smallest share (118 million yuan). The market is expected to maintain double-digit growth over the next 5-10 years, further propelled by humanoid robots [2][7] Market Dynamics - The ball screw rod market is dominated by Taiwanese, Japanese, and European and American companies, with NSK, THK, and Schaeffler accounting for 94% of the global market share. The domestic high-end ball screw rod localization rate is only 30%, indicating significant room for improvement for local companies [2][9][21] Technological Developments - Planetary roller screw rods are widely adopted in humanoid robot projects by companies like Tesla, Xiaopeng, and Xiaomi due to their high load capacity and self-locking features, particularly suitable for joints requiring high axial force [2][11][12] Design Innovations - Tesla's humanoid robot hand design may shift from a worm gear scheme to a motor with a reducer combined with C-shaped steel and tendon ropes to improve transmission efficiency, indicating a trend towards increased demand for micro C-shaped steel, with a single hand potentially requiring 17 micro screw rods [2][13] Industry Challenges and Improvements - The screw rod processing industry faces challenges such as internal thread grinding precision and efficiency. The industry is actively exploring new processing methods to enhance efficiency and reduce costs, including the use of lightweight materials like PEEK [4][15][19] Future Market Potential - The application of micro screw rods in robots is expected to grow significantly, with projections indicating that if humanoid robot production reaches 1 million units annually, the market for micro screw rods could reach 28 billion yuan. If production reaches 3 million units, the market potential could exceed 50 billion yuan [14][24] Key Players and Developments - Major domestic players in the screw rod industry include Hengli Hydraulic, Shuanglin Co., Huichuan Technology, Best, Beite Technology, and Wuzhou Xinchun, all actively expanding their screw rod and related businesses [22][24] Conclusion - The screw rod industry is poised for significant growth driven by advancements in humanoid robotics and increasing demand for high-performance screw rod solutions. The market dynamics indicate a shift towards domestic production and innovation, with substantial opportunities for local manufacturers to capture market share in high-end applications [2][21][24]
