Amid this transformative wave, MTWB (Mighty Way Industrial Limited) —— a seasoned OEM bearing supplier and customized bearings manufacturer——is emerging as a key partner for industries demanding precision, reliability, and tailored solutions.
China Domestic Market:
Accelerating Import Substitution with Dual Drivers of Capital and TechnologyThe domestic ultra-precision miniature bearing sector in China is experiencing a remarkable surge, characterized by technological breakthroughs, aggressive capacity expansion, and significant capital market activities.
Enterprise Financing and Capacity Expansion
Leading players are securing substantial funding to scale operations:
■Nantong Shankou Jinggong completed a hundreds-of-millions-yuan Series C financing round in May 2026, with strategic investments from industry giants including BYD. The company's production capacity has skyrocketed from under 500,000 units in 2005 to an impressive 300 million units today.
■Ningbo Silver Ball Technology has consistently invested in recent years, securing the world's second-largest and China's largest market share in high-speed miniature bearings. The company has achieved mass production of ultra-high-speed miniature bearing units reaching 200,000 RPM.
■Suzhou Tiejin completed a strategic financing round of nearly 200 million yuan in 2025.
Technological Breakthroughs and Product Innovation
Domestic enterprises are achieving remarkable milestones in core technologies:
■ Speed Records: Ningbo Daler Mechanical Technology Co., Ltd. now produces ultra-high-speed miniature ball bearings exceeding 150,000 RPM.
■Extreme Speed Limits: Silver Ball Technology, in collaboration with Nanjing University of Aeronautics and Astronautics, has developed a prototype ultra-high-speed bearing unit with an internal speed of 550,000 RPM.
■Core Patents: Beining Intelligent Technology has secured a patent for a "Special Ultra-Miniature High-Speed Motor Bearing," designed to enhance motor performance and service life. Ningbo Sijie Precision Technology has also obtained relevant invention patents.
■Domestic Substitution Breakthrough: Shankou Jinggong successfully developed a high-speed long-life bearing for 5G equipment cooling fans, achieving a lifespan of 70,000 hours and effectively replacing imported alternatives.
Market and Application Expansion
Domestic bearings are penetrating increasingly sophisticated applications:
■Hunan Nanguang Precision's ultra-miniature bearings are now utilized in drones (including DJI products) and robot dexterous hands.
■Silver Ball Technology's products have found applications in aerospace equipment, LiDAR systems, and high-end vacuum cleaners.
Global Dynamics: Industry Giants Lead with Deep Investments in Frontier Applications
International news from traditional bearing powerhouses reveals strategic commitments to ultra-high-speed technologies and emerging high-growth sectors such as AI and electric vehicles.
To meet the demands for miniaturization and lightweighting in EVs, global giants are pushing the boundaries of ultra-high-speed bearings:
■ JTEKT launched an ultra-high-speed deep groove ball bearing for e-Axle systems in May–June 2026, achieving a maximum speed of 40,000 RPM. The cage deformation is reduced by approximately 70% compared to current products.
■NTN showcased at its July 2026 Tokyo exhibition a bi-directional hydrodynamic bearing and the world's smallest hydrodynamic bearing, "Hydrodynamic BEARPHITE" (with an inner diameter of 0.6 mm), both supporting high-speed rotation.
The cooling demands of AI data centers are creating a massive new market for high-speed miniature bearings:
■MinebeaMitsumi announced in July 2026 a $360 million investment to build a factory in Southeast Asia, dedicated to producing precision bearings for AI data center equipment such as server fans. The company plans to increase overall capacity by 30%, pushing monthly production beyond 500 million units.
Miniature bearings are indispensable in aerospace and other sectors where weight and precision are paramount:
■ Industry experts emphasize that in aerospace systems such as gyro stabilizers and navigation devices, miniature bearings with diameters of just a few millimeters are critical components ensuring precision and stability under high-speed rotation.
