Structural Characteristics
  • Application of High-performance Materials: Advanced special alloy materials are used, which have outstanding strength and excellent toughness. They can easily handle the huge centrifugal force at ultra-high rotational speeds, as well as the strong impacts caused by frequent start-stop and speed changes, ensuring the overall structure of the bearing is stable and reliable.
  • Ultra-precision Rolling Element Design: The rolling elements are made of top-notch ceramics or deeply optimized steel materials. The surface finish is extremely high, and the hardness far exceeds the norm, greatly reducing the friction coefficient and making wear negligible, laying a solid foundation for ultra-high-speed and smooth rotation.
  • Precision-guided Cage: The cage is mostly carefully made of lightweight and high-strength composite materials. Its unique structure accurately controls the movement trajectory of the rolling elements, preventing collisions and friction between the rolling elements. Even during extremely fast operation, it can maintain excellent dynamic balance.
  • Extremely Precise Ring Process: The rings go through multiple strict ultra-precision grinding and heat treatment processes. Various form and position tolerances are controlled within a very small range. For example, the roundness and cylindricity are nearly perfect, and the close fit with the rolling elements achieves unparalleled rotational accuracy.
Performance Advantages
  • Outstanding Extreme Speed Performance: Specifically designed to break the speed limit, it can operate stably at astonishing ultra-high speeds for a long time, precisely meeting the demanding requirements for extreme speeds in fields such as aircraft engines and cutting-edge high-end equipment.
  • Ultra-long Durability and High Reliability: Relying on top-notch materials and exquisite craftsmanship, it has extraordinary fatigue resistance and corrosion resistance, greatly reducing the frequency of maintenance and safeguarding the long-term efficient operation of the equipment.
  • Ultra-low Vibration and Silent Operation: Thanks to the precise cooperation between all components, the vibration and noise during high-speed operation are suppressed to an extremely low level that is almost inaudible, creating a quiet and efficient working environment.
Application
The bearings can be used in the following industries
  • Aerospace: It is the best choice for the core rotating parts of aircraft engines and the high-speed attitude control mechanisms of aircraft, helping flying machines achieve high-speed and precise movements and ensuring flight safety and efficiency.
  • High-end Manufacturing: It shines in the high-speed electric spindles of precision CNC machining centers and high-end grinding machines, as well as the high-speed rotating units of semiconductor manufacturing equipment, enabling high-precision and high-efficiency industrial production.
  • New Energy Vehicles: It is suitable for the high-speed bearing positions of drive motors, fearless of frequent start-stop and ultra-high rotational speed working conditions, injecting strong power into the power upgrade and range extension of new energy vehicles.
