71808 thin‑walled angular contact ball bearing is designed for space‑limited mechanical structures, it bears radial load and unidirectional axial load. Characterized by low noise and high limiting speed, widely used for fan spindles, small gear assemblies and general precision industrial machinery.

71800 series bearings feature an angular contact design with ultra-thin section dimensions, engineered to support combined radial and axial loads in an extremely lightweight, space-saving package. Available in open configurations only, with bore diameters ranging from 10mm to 50mm and an ultra-thin cross-section height of 5mm across all sizes. These bearings deliver compact design, significant weight reduction, high-speed capability, excellent axial rigidity, and reliable performance in precision applications, making them ideal for aerospace actuators, robotics joints, medical imaging equipment, semiconductor manufacturing devices, machine tool spindles, and high-speed precision mechanisms where both weight savings and axial load capacity are critical requirements.
