Precision bearings are specialized bearings designed to provide high-precision rotation and high-performance operation for equipment. This high-precision rotation reduces friction, ensuring smooth operation and improving efficiency. They are primarily used in equipment requiring extremely high rotational accuracy, speed stability, and smooth operation, such as CNC machine tools, aerospace systems, medical instruments, robotics, and precision measuring equipment.
