Ⅰ. One Bearing = Three Loads: AVE "Structural Magic" is Powerful
In the precision rotating parts of industrial equipment, there lies a versatile performer: the AVE crossed roller bearing. Its unique 90° cross-roller roller arrangement achieves a trinity of load-bearing capacity: radial load, axial load, and overturning moment. This delivers 3-5 times greater rigidity than traditional bearing combinations, and rotational accuracy reaches P2 (angular measurement accuracy as low as 2 arc seconds). More importantly, this minimalist design allows for equipment reduction: the CRBT series is only 5mm wide, while the RB series achieves extreme miniaturization through its "integrated inner ring, split outer ring" construction. This reduces parts count by over 50% compared to traditional bearing combinations, slashing installation time by half. From robotic joints to aerospace equipment, it delivers high precision in a compact package.
II. Deep Penetration into Five Core Areas, Unlocking the Secrets of High-End Manufacturing
1. Industrial Robots: The "Precision Bones" of Joints
The flexible swinging of humanoid robots and the chip insertion and removal of collaborative robots all rely on bearings to maintain a steady rhythm. Aoweit offers customized solutions for different robotic scenarios:
• RAU bearings feature a one-piece inner and outer ring design, simplifying installation and adapting to the rotating parts of lightweight and small service robots;
• Bearings specifically designed for harmonic reducers achieve P2-level precision. With a flexible bearing wall thickness of only 2-5mm, they can withstand 8% cyclic deformation, keeping the transmission error of a 10kg robotic arm within 1 arc minute.
At the 2025 Hangzhou Humanoid Robot Exhibition, its spherical bearings became a key component in breaking through bottlenecks in domestically produced robots.
2. Precision Machine Tools: The "Stabilizer" of Micron-Level Machining
Five-axis machining on high-end machine tools requires no tolerance for vibration. AVE bearings play a core role in CNC rotary tables and direct-drive motor rotary tables:
• When supporting vertical machining center rotary tables, they can control the cylindricity of turbine blades within 0.003mm.
• Specialized bearings for direct-drive motor rotary tables feature a hollow structure with reserved coolant channels, enabling nanometer-level positioning (such as wafer dicing), while maintaining a 30% lower temperature rise than traditional bearings.
No wonder they have become the "standard" for simultaneous development by high-end machine tool companies.
3. Aerospace: A "Reliable" Bearing in Extreme Environments
Aircraft parts processing and radar rotary tables place extremely stringent requirements on bearing reliability. AVE YRT rotary table bearings, with their "thrust-centripetal" combined structure, achieve P2-level precision in aerospace workshops, enabling micron-level inspection of radar components using coordinate measuring machines. Their impact-resistant carburized steel material withstands extreme temperature fluctuations and vibration environments, making them the invisible cornerstone of these "national treasures."
4. Medical Devices: Invisible Assistants for Precision Operations
AVE thin-walled crossed roller bearings are highly effective in surgical robots and precision testing instruments. Their ultra-thin CRBH design (width 8-13mm) meets the lightweight demands of medical equipment, with a rotational accuracy of ≤0.001mm, ensuring precise positioning of minimally invasive surgical instruments. From precision tumor radiotherapy to gene sequencing equipment, they inject precision into medical technology.
5. Automation Equipment: The Accelerator for Efficient Production
Core automation components such as direct-drive motors and hollow rotary platforms rely on the efficient support of bearings. AVE XSU bearings are suitable for high-speed operation, with a DN value of up to 1.5×10⁶ and 70% less friction loss than plain bearings. In semiconductor wafer processing lines, the rotary platforms they support achieve 24-hour continuous precision operation, increasing yield rates by 15%.
III. From Luoyang to the World: The Breakthrough of Domestic Precision Bearings
As a backbone of the Luoyang bearing industry cluster, AVE has built a comprehensive product portfolio covering P5-P2 grades, boasting ISO 9001 certification and concurrent R&D capabilities. From industrial robots to aerospace, from domestic exhibitions to the international supply chain, its crossed roller bearings are gradually replacing imported products, demonstrating the strength of domestic bearings with millimeter-level precision.
While marveling at the precise "embroidery" of robots and the mirror-like finish of machine tools, remember that behind them lies the "rotating power" of AVE bearings.
