I. Strategic Emerging Fields: The Next Growth Pole for the Bearing Industry

The global bearing industry is at the threshold of a new round of technological revolution. As the growth in traditional industrial sectors becomes stable, strategic emerging fields such as semiconductor equipment, low-altitude economy, humanoid robots, and data center cooling are becoming the most explosive growth poles for the bearing industry. The global high-end bearing market has exceeded 98 billion US dollars by 2025. These high-growth sectors are continuously raising the requirements for bearings - higher precision, higher rotational speed, wider temperature range, and stricter cleanliness.

 

NMT, a Japanese company, has been deeply involved in the bearing industry for nearly a hundred years. With its systematic capabilities in material purification, process refinement, scenario customization, and intelligent upgrading, it provides high-precision, low-noise, and long-life precision bearing solutions for strategic emerging fields.

 

II. Semiconductor Equipment: Pollution-Free Precision Transmission in a Vacuum Environment

Semiconductor manufacturing equipment is one of the most technologically demanding sub-sectors in the bearing industry. Lithography machines, etching machines, ion implantation machines, and wafer handling equipment need to adapt to the extremely harsh working environment in the chip manufacturing process - ultra-high vacuum, extreme temperatures, corrosive chemical gases, and strict ISO 1-level cleanroom standards. To prevent the chips from being contaminated, bearings need to be made from special materials and equipped with vacuum-level lubrication technology.

 

The global sales of specialized bearings for semiconductor equipment reached 247 million US dollars in 2025, and are expected to reach 334 million US dollars by 2032. The sliding bearing market for semiconductor equipment is also growing rapidly, with a global revenue scale of approximately 2.814 billion yuan in 2025, approaching 4.787 billion yuan by 2032. The global market for air bearings for main shafts was approximately 478 million US dollars in 2025, and is expected to reach 843 million US dollars by 2032.

 

In these extreme environments, every performance of the bearing is crucial for the chip's yield. The trace organic substances that evaporate from ordinary bearings in a vacuum may deposit on the chip surface, causing irreversible contamination defects. NMT's specialized bearing for semiconductor equipment adopts a combination of high-purity stainless steel and ceramic materials to ensure extremely low gas release rate and particle emission; solid lubrication or low-volatile lubrication schemes completely eliminate the risk of oil evaporation; ultra-precision processing and micro-gap design ensure reliable transmission under nanometer-level positioning accuracy. From materials to lubrication, from precision to cleanliness, NMT provides comprehensive technical support for semiconductor manufacturing.

 

III. Low-altitude Economy: A Must-have for Bearings in the Trillion-Dollar Sector

Low-altitude economy has become one of the most closely watched emerging sectors since 2025. Against the backdrop of the country's vigorous development of low-altitude economy, the overall scale of China's low-altitude economy is expected to exceed 1.5 trillion US dollars in 2025. Currently, there are over 112,000 registered industrial drones in China, and nearly 20 leading eVTOL enterprises are accelerating mass production. The annual compound growth rate of the aviation self-lubricating bearing supporting market is expected to reach 37% in the next three years.

 

The working environment of low-altitude aircraft is extremely harsh. The motor of the unmanned aircraft can rotate at tens of thousands of revolutions per minute, and the supporting bearings need to withstand extremely high dynamic loads while ensuring stable operation at ultra-high rotational speeds. Traditional grease-lubricated bearings require maintenance every 50-80 flight hours and are prone to failure in extreme conditions such as -60℃ cold and coastal salt fog. Wanwei Qianchao has completed the sample delivery of multiple types of bearings for the transmission system of a certain leading low-altitude heavy-load manned/unmanned helicopter. The product types are mainly deep groove ball bearings and tapered roller bearings.

 

The temperature difference between the ground and high altitude in low-altitude aircraft requires bearings to maintain reliable operation in the wide temperature range of -60℃ to high temperature. NMT's wide-temperature lubrication system maintains stable lubrication performance between high-temperature ground and low-temperature high altitude; special heat-stabilizing treated steel ensures the bearing's size stability in extreme temperature differences; lightweight design and high-purity materials balance weight reduction and reliability. From airworthiness testing to mass production, NMT is providing reliable transmission support for the takeoff of the low-altitude economy.

 

IV. Humanoid Robots: The Super赛道 with a Compound Growth Rate of 46.6%

Humanoid robots are the most imaginative track in the current bearing industry. The global market sales of humanoid robot bearings will be approximately 0.33 billion US dollars in 2025， and is expected to reach 8.70 billion US dollars in 2032， with a compound annual growth rate of 46.6%. The joint bearing market for humanoid robots will be approximately 0.53 billion US dollars in 2025， and is expected to reach 6.6 billion US dollars in 2032， with a compound annual growth rate of 44.0%.

 

The joints of humanoid robots must provide high torque， a wide range of motion， and precise and repeatable positioning under complex multi-directional loads. Compared with traditional industrial robots， humanoid robot bearings must operate in a highly compact ergonomic shape space， withstand complex combinations of radial， axial， and overturning loads， and support low friction and low noise movements. The humanoid robot bearing market covers deep groove ball bearings， four-point contact bearings， angular contact bearings， cross roller bearings， flexible bearings， etc. Among them， the cross roller bearing is the characteristic structure of the humanoid joint - through 90° cross arrangement of cylindrical rollers， it can simultaneously withstand radial， axial， and torque loads， and is very suitable for core parts such as hip joints， knee joints， shoulder joints， and wrist joints.

 

NMT and other thin-walled bearing sections are specifically designed for humanoid robots. The cross-sectional dimensions of the thin-walled bearing sections do not change with the increase in installation diameter. Designers can make the joints thinner， lighter， and larger with hollow shapes while not sacrificing rigidity. The cross roller bearing uses a parallel arrangement structure of cylindrical rollers to simultaneously withstand multiple dimensions of loads. NMT introduces a positioning pre-tightening structure on the outer ring of the cross roller bearing， using the height difference between the end faces of the inner and outer rings to form a calculable elastic compression amount， ensuring the consistency of assembly pre-compression effect. From the laboratory prototype to the mass-produced humanoid robots， NMT is providing precise underlying support for each joint movement.

 

V. Data Center Cooling： The Energy Efficiency Revolution Driven by Magnetic Levitation Bearings

The explosive growth of AI large models is pushing the cooling pressure of data centers to unprecedented heights. Driven by the "East Data West Computing" project and the explosion of AI computing power leading to the popularization of high-density cabinets， it is expected that the market size of magnetic levitation compressors for data centers in China will increase from 63.0 billion US dollars in 2024 to 218.1 billion US dollars in 2030， with an average annual compound growth rate of 23.0%. The global market size of magnetic levitation compressors for data centers in 2025 is approximately 3.4 billion US dollars， and is expected to reach 7.45 billion US dollars in 2032. The market size of magnetic levitation chillers for data centers is expected to increase from 4.06 billion US dollars in 2025 to 12.62 billion US dollars in 2032.

 

Magnetic levitation compressors use magnetic levitation bearing technology to suspend the rotor of the compressor， achieving non-contact operation and eliminating mechanical friction. Compared with screw compressors， the comprehensive part-load performance coefficient of magnetic levitation units is improved by approximately 42%， helping data centers achieve a PUE reduction to 1.2. Magnetic levitation bearings have revolutionary advantages such as no contact， zero friction， and no lubrication， and are particularly suitable for high-speed， vacuum， and ultra-clean environments. Danfoss' data center-related business in China grew threefold in 2024 and is expected to grow at a rate of approximately 50% in 2025.

 

NMT's technical accumulation in the field of precision bearings has laid a solid foundation for expanding into more advanced directions such as magnetic levitation bearings. From precision rolling bearings to magnetic levitation bearings， NMT continuously expands the technical boundaries of precision transmission. The NMT bearings can cover the aforementioned diverse strategic emerging fields due to the inherent underlying universality of their technical system - high precision, low noise, long lifespan, and resistance to extreme environments.

 

High purity steel is the cornerstone of performance. NMT uses vacuum degassing high-carbon chromium bearing steel, and through precise forging and secondary quenching processes, reduces the content of non-metallic inclusions in the material to an extremely low level, increasing the fatigue resistance by 38% compared to ordinary products. After special heat treatment by "Ottabain", the surface hardness of the bearings reaches HRC62-64, improving the anti-wear performance by 40%, while the core strength ensures that it does not fracture under high-frequency impact loads. The rated lifespan is more than twice that of industry standards.

 

Ultra-precision manufacturing converts material advantages into actual performance. After nanometer-level ultra-finishing of the raceways, the surface roughness is controlled within 0.01 μm, and the rotational accuracy reaches the high standard of ISO P2. The retainers are optimized through dynamic characteristic simulation, with the friction coefficient reduced to 0.0015, and the operating noise controlled within 20 dB.

 

Full-scenario sealing and lubrication are adapted to the needs of different tracks. NMT provides a full-spectrum range of solutions including IP54 level basic dust protection, IP68 level high-pressure waterproof, and fluorine rubber seals.
