Micro bearings usually refer to small-sized bearings with an inner diameter of less than 10 millimeters and an outer diameter of less than 26 millimeters, widely used in precision machinery, small motors, medical devices, and other fields
High precision requirements: The machining accuracy needs to reach P5 level or above, with precise clearances between parts and high manufacturing difficulty
Material selection: commonly used stainless steel or ceramic hybrid materials to ensure corrosion resistance and cleanliness, suitable for sensitive scenarios such as medical and electronics
Performance requirements: low friction, low noise, high speed (high DMN value), suitable for fast start stop devices such as drones and fans
