丝杠行业深度报告：人形机器人催化丝杠国产化，优质企业乘势而上

Investment Rating - The report recommends investing in the screw rod industry, highlighting the potential for domestic companies to gain market share as the demand for high-end machine tools and humanoid robots increases [3]. Core Viewpoints - The screw rod is a core linear drive component with high technical barriers, and the domestic production rate is lower compared to other core components. The growth in high-end machine tools and the development of humanoid robots are expected to drive demand for screw rods, particularly planetary roller screw rods, which are projected to exceed 45 billion yuan by 2030 [2][3]. - The report identifies key companies for investment, recommending Fuda Co., Ltd. and Beite Technology, while suggesting to pay attention to Shuanglin Co., Wuzhou Xinchun, Rongtai Co., and Zhenyu Technology [3]. Summary by Sections Industry Overview - Screw rods are widely used linear transmission components, categorized into trapezoidal screw rods, ball screw rods, and planetary roller screw rods. Ball screw rods have a transmission efficiency of 90%-96%, significantly higher than trapezoidal screw rods [2][6]. - The demand for screw rods is expected to grow due to stable growth in machine tools and new energy sectors, with humanoid robots opening new market opportunities [2][3]. Market Demand - The humanoid robot market is projected to create substantial demand for planetary roller screw rods, with an estimated market exceeding 45 billion yuan by 2030. European companies currently dominate the market, indicating significant potential for domestic replacements [2][3]. - The report notes that the global market for planetary roller screw rods is primarily held by foreign companies, with domestic companies like Nanjing Technology and Jining Bote holding smaller market shares [2]. Investment Recommendations - The report suggests that the screw rod industry will benefit from the increasing production of high-end machine tools and the growth of the humanoid robot sector. It recommends specific companies for investment and highlights the potential for domestic screw rod manufacturers to capture market share as the industry evolves [3][5].
