The cross-sectional design of 61808 ultra-thin wall bearings significantly reduces installation space and is the preferred bearing for lightweight precision transmission solutions. Supporting harmonic drive module, industrial small-scale indexing mechanism, optical imaging equipment, and lightweight automated rotating bracket.
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.
