The HFH KA050AR0 is a high-precision thin section radial ball bearing designed for applications requiring compact design and lightweight components. Featuring a 127 mm (5.000 inch) bore, 139.7 mm (5.500 inch) outer diameter, and a narrow 6.35 mm (0.250 inch) width, this bearing offers excellent radial load capacity. Its thin cross-section minimizes space requirements and reduces overall system weight, making it suitable for robotics, aerospace, medical equipment, and other industrial machinery where space and weight are critical.
