The NACHI 5305-2NS is a double-row angular contact ball bearing designed for demanding applications requiring high axial and radial load capacity. It features a 25 mm bore, 62 mm outside diameter, and 25.4 mm width, with two integral seals for enhanced protection against contaminants. The bearing offers a 20-degree contact angle, a dynamic load rating of 32,000 N, and a static load rating of 21,600 N, ensuring reliable performance under heavy loads. Constructed from durable steel, it operates at speeds up to 7,300 rpm (grease) or 10,000 rpm (oil), and is precision-rated to ABEC 1 (ISO P0) for consistent, smooth rotation. Ideal for industrial machinery, blowers, and high-speed applications, the 5305-2NS combines robust construction, sealed design, and high load capacity in a compact package.
