In the intricate chain of industrial manufacturing, bearings act as the "joints" supporting the operation of mechanical equipment. From the wheels of high-speed trains to the rotors of wind turbines, from the drive motors of new energy vehicles to the joint modules of industrial robots, the performance of bearings directly determines the reliability, efficiency, and service life of equipment. According to the 2025-2030 In-depth Market Research and Investment Potential Study Report on the Bearing Industry by CIN Research Institute, China's bearing market scale exceeded 316.5 billion yuan in 2024, accounting for over 30% of the global market share. However, high-end products still rely on imports, with a domestic substitution space of $12 billion. Behind this contradiction lies a critical transition period for China's bearing industry from "scale expansion" to "value leap."

Current Market Development: A Tale of Two Extremes in a Trillion-Dollar Industry

• Scale and Landscape: China's Strength in the Global Industrial Chain
  By 2025, China's bearing production is expected to exceed 30 billion sets, accounting for over 40% of the global total, but its output value accounts for only 30%, reflecting the hidden concern of "large but not strong." The five major industrial clusters in Wafangdian (Liaoning), eastern Zhejiang, Suzhou-Wuxi-Changzhou (Jiangsu), Liaocheng (Shandong), and Luoyang (Henan) contribute 60% of the national production capacity. Among them, eastern Zhejiang's micro bearings hold a 65% global market share, and Liaocheng (Shandong) supplies 70% of the national bearings for accessories like cages and steel balls. Market concentration needs improvement: there are over 12,000 bearing enterprises in China, but the top 10 account for only 30% of the market share, with C&U Group leading at 12%. In contrast, the world's eight major multinational enterprises (SKF, Schaeffler, NSK, etc.) dominate 75% of the global market, monopolizing high-end sectors.

• Technological Breakthroughs: From "Following" to "Running Parallel"
  Breaking into high-end sectors: Luoyang LYC's high-speed railway bearings have passed a 1.2 million-kilometer bench test, with performance comparable to top international products. Xinqianglian's megawatt-level wind turbine bearings have achieved localization of main shaft bearings for 15MW models, with unit prices exceeding 2 million yuan, breaking overseas monopolies. Material and process upgrades: Baowu Steel and Ansteel's mass-produced G20CrMoA bearing steel has seen a 30% improvement in purity compared to five years ago, but still lags behind Japan's Sanyo Special Steel in inclusion control and structural uniformity. Wuzhou Spring has introduced an AI visual inspection system, improving bearing defect recognition accuracy to 99.97% and yield rate to over 98.5%.

• Demand Stratification: Dual Drivers of Traditional and Emerging Sectors
  Steady growth in traditional sectors: The automotive bearing market exceeds 200 billion yuan, accounting for over 40% of the industry's total scale. New energy vehicles have seen a threefold surge in demand for 800V high-voltage platform insulated bearings, with drive motor bearing prices 50% higher than traditional fuel vehicles.

Development Prospects: Triple Resonance of Policy, Technology, and Market

• Policy Dividends: From "Filling Shortcomings" to "Forging Strengths"
  Accelerated domestic substitution: The Implementation Opinions on Improving Manufacturing Reliability explicitly lists high-speed rail and aviation bearings as "necklace-breaking" key projects. In 2024, the central government established a 10-billion-yuan special fund, offering a 15% R&D subsidy to enterprises that break through P4-level precision bearing technologies.

• Technological Revolution: From "Mechanical Components" to "Smart Terminals"
  Intelligent upgrades: C&U Group's smart bearings with built-in sensors can real-time monitor temperature and vibration data, with a warning accuracy rate of 92%. These have reduced unplanned downtime by 30% in Baowu Steel's blast furnace equipment. This "product service" model has a gross profit margin exceeding 40%, 18 percentage points higher than traditional manufacturing.

• Market Demand: From "Functional Needs" to "Value Needs"
  High-end equipment demand: The aviation and aerospace bearing market is expected to reach 50 billion yuan by 2025, while the energy sector (wind and nuclear power) bearing market will exceed 80 billion yuan, with surging demand for high-temperature, corrosion-resistant, and lightweight bearings. Driven by consumption upgrades: The household appliance bearing market is approximately 60 billion yuan, with consumer demand for low-noise and long-life bearings boosting the penetration rate of precision products like ball screws and linear guide bearings.

Future Trends: Four Directions Reshaping the Industrial Ecosystem

• Upgrading to High-End: From "Low-Medium End Involution" to "Climbing the Global Value Chain"
  Technological breakthroughs: High-end products such as P4-level precision bearings, aviation/aerospace bearings, and nuclear power main pump bearings will accelerate domestic substitution. By 2030, the localization rate of high-end bearings is expected to rise from 20% to 50%. Standard setting: China Bearing Industry Association, together with leading enterprises, has formulated group standards such as Technical Specifications for High-Speed Railway Bearings and Standards for Humanoid Robot Joint Bearings, promoting Chinese standards globally.

• Intelligentization: From "Single-Machine Intelligence" to "System Interconnection"
  Industrial internet integration: Bearing enterprises use IoT technology to connect equipment, collect data on temperature, vibration, and load, and build predictive maintenance models. A wind power enterprise reduced maintenance costs by 40% through a bearing condition monitoring system. Digital twin applications: Luoyang LYC uses digital twin technology to simulate the full lifecycle operation of bearings, optimizing heat treatment process parameters and increasing bearing fatigue life by 25%.

• Green Transition: From "Energy Conservation" to "Circular Economy"
  Environmentally friendly material substitution: The market share of green products such as ceramic hybrid bearings and polymer self-lubricating bearings has increased from 5% in 2020 to 15% in 2025, reducing reliance on traditional lubricants. Remanufacturing systems: C&U Group has established a bearing remanufacturing base, repairing used bearings through laser cladding and plasma spraying technologies at only 30% of the cost of new products. In 2024, remanufactured bearing sales exceeded 500,000 sets.

In 2025, China's bearing industry is no longer a traditional "mechanical parts supplier" but has become the "heart" of high-end equipment, the "neuron" of smart manufacturing, and a "practitioner" of the green economy. From the "Chinese core" of high-speed rail bearings to the "flexible dancers" of humanoid robot joints, from the "anchor of stability" for wind turbines to the "oil-free dream" of hydrogen energy equipment, every breakthrough is redefining the boundaries of this trillion-yuan market.

CIN Research predicts that by 2030, the total output value of China's bearing industry chain will exceed 500 billion yuan, with high-end bearings accounting for 40% and smart bearings having a penetration rate of over 30%.
