A flange bearing is a mechanical component that integrates a flange with the bearing design, featuring an outer wheel with a flange structure, offering easy axial positioning and the advantage of not requiring an additional bearing housing. This product employs small outer diameter steel balls to reduce friction torque, enhance rigidity, and improve rotation accuracy, achieving lightweight design and providing space for wiring through a hollow shaft design. igus, the motion plastics experts, launched the new igubal flange bearing in July 2025, which has improved ease of replacement. The standard size is ABEC-1 grade, characterized by simple structure and cost-effectiveness. By improving the keeper gap design, optimizing keeper strength, and adding guide grooves, the service life can be extended. Its application spans precision machinery fields such as industrial equipment, miniature motor soft drives, hard disk motors, robots, and medical devices, with a unique advantage in scenarios where flat mounting at the shaft end is required.
