Miniature Metric Series, Single Row Deep Groove Ball Bearing with Two Shields - (3x10x4 mm)

623-ZZ is a 620 miniature series double shielded single row deep groove radial ball bearing with a 3 mm bore, 10 mm outside diameter, and 4 mm width. Built with precision-ground raceways and steel balls for smooth, low-friction rotation in very small shaft assemblies. Double metal shields help retain lubricant while reducing running drag compared with rubber sealed designs, making this bearing suitable for compact high-speed applications. Commonly used in RC cars, 3D printers, small motors, model equipment, and precision mechanisms.
