This deep groove ball bearing carries radial and moderate axial loads on a 10.0 mm bore, 30.0 mm outside diameter and 9.0 mm width, weighing 33.0 g. The single-row design uses a steel sheet metal cage (JN) and seals on both sides (2RSR), which retain the internal grease fill and keep out contamination. The radial internal clearance is CN (Group N), the standard clearance group, and the bore type is Z. Limiting speed is rated at 16100.0 1/min. Because the bearing is sealed on both sides, it runs without additional relubrication and stays protected from dust and moisture, which suits applications where the housing cannot be maintained regularly. The standard CN clearance makes it suitable for typical shaft and housing fits without special preload requirements, and the steel sheet metal cage keeps the balls guided reliably at the stated limiting speed.
