This deep groove ball bearing carries radial and moderate axial loads on a single row of balls running in a heavier cross-section 62310 series construction. Bore diameter is 50.0 mm, outside diameter 110.0 mm, width 40.0 mm, with a net mass of 1.578 kg. The cage is a steel sheet metal type (JN), and the limiting speed is rated at 3950 1/min. The bearing is fitted with seals on both sides (2RSR), which keep grease inside and block contaminants from entering the raceway, so no external sealing arrangement is required. Radial internal clearance falls in group CN, suitable for standard fit and temperature conditions without extra clearance adjustment. Dimensionally and constructionally it corresponds to SKF 62310-2RS1, NSK 62310DDU, and NTN 62310LLU.
