Ceramic bearings have multiple applications in the field of space, and the following are some common application scenarios:1. Spacecraft attitude control system: The spacecraft attitude control system is responsible for maintaining the correct positioning and direction of the spacecraft. Ceramic bearings play a crucial role in attitude control systems, supporting and controlling the rotational motion of attitude control devices, ensuring the stability and accuracy of the attitude control system.2. Vacuum pumps and centrifuges: Equipment such as vacuum pumps and centrifuges are required for space simulation experiments and fuel refueling of spacecraft. Ceramic bearings are widely used in the rotating parts of these devices to provide stable motion, low friction, and high-precision rotation, ensuring experimental accuracy and safety.3. Satellite communication antenna: The antenna in a satellite communication system requires accurate pointing and positioning. Ceramic bearings are used to support and control the rotational motion of antennas, providing high-precision directionality and stability to ensure the reliability and performance of communication systems.4. Engine components: In rocket engines and jet thrusters of spacecraft, ceramic bearings are used to support key components such as high-speed rotating turbines and turbine blades. Ceramic bearings ensure smooth operation and propulsion of the engine by providing high rigidity, high temperature resistance, and low friction characteristics.5. Spacecraft orbit adjustment system: Spacecraft require orbit adjustment and attitude control in space. Ceramic bearings are used in the attitude adjustment system of spacecraft, providing high-precision motion control and stability to ensure accurate orbit adjustment and position positioning of the spacecraft. The application of ceramic bearings in the space field aims to provide high-precision, high stability, and durable motion control to ensure the reliability and performance of spacecraft in environments and demanding missions.
