【重磅深度】人形机器人催化丝杠国产化，优质企业乘势而上

Core Viewpoint - The screw rod, as a core linear drive component, has a high technical barrier in its thread processing technology, which is crucial for its manufacturing and application across various industries such as machine tools, aerospace, robotics, and automotive [2][6]. Group 1: Screw Rod Types and Applications - Screw rods can be categorized into three types based on friction characteristics: trapezoidal screw rods, ball screw rods, and planetary roller screw rods, with ball screw rods achieving a transmission efficiency of 90%-96%, significantly higher than trapezoidal screw rods [2][6]. - Planetary roller screw rods outperform ball screw rods in load capacity, lifespan, lead, space, and speed, making them suitable for high-precision and high-load applications [2][20]. Group 2: Market Demand and Growth - The demand for screw rods is expected to grow steadily due to the robust growth in machine tools and new energy sectors, with humanoid robots opening new market opportunities. The market for planetary roller screw rods is projected to exceed 45 billion yuan by 2030 [3][4]. - In humanoid robots, screw rods account for approximately 19% of the value, with a potential demand for 14 planetary roller screw rods per robot, plus additional micro planetary roller screw rods used in dexterous hands [3][4]. Group 3: Competitive Landscape - European companies dominate the planetary roller screw rod market, with significant market share held by foreign firms such as Rollvis and GSA, which together account for nearly 60% of the market in China. This indicates substantial room for domestic replacement [3][4]. - The screw rod industry has a complete supply chain, with upstream components including raw materials and processing equipment, midstream products being various types of screw rods, and downstream applications spanning automotive, humanoid robots, industrial mother machines, and more [47][48]. Group 4: Investment Recommendations - The investment outlook for screw rods is positive, with recommendations for companies such as Fuda Co., Ltd. and Beite Technology, while also suggesting to monitor companies like Shuanglin Co., Ltd. and Wuzhou Xinchun [4][6].
