The global thin-section bearings market was valued at approximately US$1.137 billion in 2025 and is projected to reach US$1.633 billion by 2032, growing at a compound annual growth rate (CAGR) of 5.4%.
According to industry data, China industrial robot joint module market alone has surpassed RMB 12 billion (approx. US$1.7 billion) in 2025, with annual demand for ultra thin-section bearings exceeding 20 million sets. The humanoid robot bearings market is forecast to grow at an extraordinary **CAGR of 45.7% , from US$14.1 million in 2025 to US$469 million by 2032.
China ultra-precision miniature bearing sector is witnessing a wave of technological breakthroughs and capital inflows, accelerating domestic substitution across strategic industries.
●Luoyang Hongyuan Bearing HRAU-series thin-section crossed roller bearings—with a cross-section of just 5mm—have become critical components in humanoid robots. These bearings powered Honor Robotics to set a new record of 50 minutes 26 seconds at the 2026 Beijing Humanoid Robot Half Marathon, and enabled Unitree Robotics' acclaimed cluster performance at the 2026 Spring Festival Gala.Hongyuan commands over 90% market share in robotics bearings, with business growth exceeding 120% in 2025.
●In May 2026, Saibei (Shandong) launched a P4-class ultra thin-section stainless steel bearing (25×37×7mm, weighing just 0.022kg) featuring a four-point angular contact design, ideal for precision automation, medical devices, and semiconductor equipment.
●Taide Shares announced it has overcome two core manufacturing challenges—thin-wall deformation and heat treatment—achieving full-chain independent R&D and production capabilities for flexible bearings, securing the industrialization of harmonic reducer bearings.
●Fuyoute (Luoyang)developed a CNC grinding production line specifically for aerospace ultra thin-section bearing rings. The line achieves machining precision within 0.0005mm on ring walls as thin as 0.5–2mm, increasing efficiency by 5–10 times while reducing costs from tens of millions to under one million yuan.The system has been operating stably at Luoyang Juchuang for nearly one year.
●Luoyang Jiawei Bearing secured a patent in June 2026 for a "high-stability corrosion-resistant single-point mooring ultra thin-section bearing device," targeting marine engineering and other demanding environments.
●Goldtek, a South Korean precision bearing company, announced in July 2026 its entry into the humanoid robot market as the exclusive Asian distributor for US-based RBC Bearings.Reports indicate that a single humanoid robot can incorporate up to 104 bearings, with more than half replaceable by thin-section alternatives. RBC's thin-section bearings are already deployed in Tesla's Optimus and other major humanoid robot platforms.
●At the ILA Berlin Aerospace Exhibitionin June 2026, Rodriguez showcased its thin-section bearing solutions, highlighting years of deployment on the International Space Station (ISS) robotic arms.
●At DSEI 2025, Carter Manufacturing demonstrated its Silverthin thin-section bearings, emphasizing their critical value in weight reduction and space optimization for satellite systems and radar equipment in aerospace and defense applications.
