Flange bearing is a mechanical component that integrates flange and bearing design. Its outer wheel has a flange structure, which has the characteristics of easy axial positioning and no need for additional bearing seats. This product uses small outer diameter steel balls to reduce friction torque, improve rigidity and rotation accuracy, and achieves lightweight and wiring space through a hollow shaft design. Sports plastic expert igus will launch a new type of igubal flange bearing in July 2025, which will improve the convenience of replacement. The standard size is ABEC-1 grade, with a simple structure and strong economy. By improving the gap design of the retainer, optimizing the strength of the retainer, and adding guide grooves, the service life can be extended. The application scenarios cover precision mechanical fields such as industrial equipment, micro motor soft drives, hard disk motors, robots, and medical equipment, especially in scenarios where flat fixation is required at the shaft end, which has unique advantages.
