Bearing
In space and astronautical engineering, a bearing is a mechanical component that supports the rotation of a spacecraft's moving parts. Bearings are designed to reduce friction between two surfaces in contact, allowing for smooth and efficient movement. They are commonly used in spacecraft propulsion systems, such as in the gimbal mechanism of a rocket engine, where they support the rotation of the nozzle. Bearings are also used in reaction wheels, which are used to control the orientation of a spacecraft in space. The bearings in reaction wheels allow for precise and stable rotation, which is essential for maintaining the spacecraft's attitude. In addition, bearings are used in the deployment mechanisms of solar panels and antennas, where they support the rotation of the panels or antennas as they are extended into space.
