61821 thin-walled deep groove ball bearing ultra-thin section layout, balancing space occupation and radial support capacity, with optional precision of P5/P6. Suitable for precision measuring turntables, small and medium-sized optical equipment, automated lightweight rotating mechanisms, and medical precision equipment.
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.
