The 61801 thin-walled deep groove ball bearing adopts an equal section ultra-thin structure, with low operating friction resistance, high ultimate speed, and smooth rotation operation. Suitable for small servo motors, monitoring micro rotating gimbals, office equipment shafts, and internal rotating mechanisms of portable small medical instruments.
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.
