Structural Characteristics
  • Application of Advanced Materials: Special alloy materials are used, which have high strength and excellent toughness. They can withstand the huge centrifugal force and impact load at ultra-high rotational speeds, ensuring the structural stability of the bearing.
  • Optimized Ball Design: The balls are made of high-quality ceramics or specially treated steel materials. They have smooth surfaces and high hardness, effectively reducing the friction coefficient and wear, thus helping to achieve extremely high-speed rotation.
  • Precision Cage Structure: The cage is mostly made of lightweight and high-strength composite materials, which can accurately guide the movement of the balls, prevent collisions, and maintain good dynamic balance during high-speed operation.
  • High-precision Ring Process: The rings have undergone ultra-precision grinding and heat treatment. The form and position tolerances such as roundness and cylindricity are extremely small, and they fit closely with the balls to ensure the rotational accuracy.
Performance Advantages
  • Outstanding Ultra-high Speed Performance: Specifically designed to meet the requirements of extreme rotational speeds, it can operate stably at ultra-high speeds, meeting the strict speed requirements of cutting-edge fields such as aircraft engines and high-speed electric spindles.
  • Long Service Life and Reliability: With high-quality materials and a refined structure, it has excellent fatigue resistance and wear resistance, reducing the frequency of maintenance and ensuring the stable operation of the equipment for a long time.
  • Low Vibration and Low Noise: The precise cooperation of components can control the vibration and noise during high-speed operation at an extremely low level, improving the quality of the operating environment.
Application
The bearings can be used in the following industries
  • Aerospace: The core rotating components of aircraft engines and the high-speed attitude adjustment mechanisms of aircraft rely on it to achieve high-speed and precise operation, ensuring flight safety and efficiency.
  • High-end Manufacturing: For example, the high-speed electric spindles of precision CNC machining centers and the high-speed rotating units of semiconductor manufacturing equipment help achieve high-precision and high-efficiency production.
  • New Energy Vehicles: In the high-speed bearing parts of the drive motors, it can adapt to the working conditions of frequent start-stop and high rotational speeds, improving the power performance and cruising range of the vehicles.
