618/670 thin-walled deep groove ball bearings have an ultra large and ultra-thin structure, greatly optimizing the overall structural dimensions of large hollow equipment. Apply large-scale optical measurement equipment, large-scale automated hollow indexing mechanisms, and large-scale precision testing 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.
