71802 thin‑walled angular contact ball bearing is engineered for compact mechanical structures. It accepts combined radial and unidirectional axial loads, can be mounted in DB / DF / DT pairing configurations. It runs smoothly at high‑speed conditions, widely adopted in testing instruments, small‑size transmission and precision automation components.

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.
