This deep groove ball bearing carries radial and moderate axial loads on a shaft with a 25.0 mm bore, 52.0 mm outside diameter and 18.0 mm width, weighing 0.154 kg. It is a single row design with a steel sheet metal cage (JN) and seals on both sides (2RSR), giving a limiting speed of 7900.0 1/min. Internal clearance is CN (Group N), the standard clearance group. The integrated seals keep the factory-fill grease inside and block dirt and moisture from entering the raceway, so the bearing runs sealed for life without needing relubrication. Standard CN clearance and the JN cage suit shaft arrangements running at constant to moderate speeds without special preload requirements, while the compact 25.0 mm bore fits standard housing and shaft dimensions for this size range.
