61805 thin-walled deep groove ball bearings are made of high-purity bearing steel, with stable rotational accuracy and controllable friction torque. Widely used in lightweight harmonic reducers, medical equipment shafts, precision optical instruments, and small and medium-sized automated gimbal devices.
61800 series bearings feature a deep-groove raceway design with extra-light section dimensions, providing reliable radial load support in a space-saving, lightweight package. Available in open, shielded, and sealed configurations, with bore diameters ranging from 10mm to 50mm and a cross-section height of 5mm across all sizes. These bearings deliver compact design, low friction, smooth quiet operation, and consistent long-term performance, making them ideal for small electric motors, pumps, fans, household appliances, office equipment, medical devices, and lightweight industrial applications where space and weight reduction are important considerations.
