The N Series cylindrical roller bearings feature a single-row design with an outer ring without ribs, allowing axial displacement in both directions. Engineered for high radial load capacity and high-speed operation, these separable-design bearings are ideal for applications where the inner and outer rings require interference fits. Widely deployed in machine tool spindles, electric motors, and industrial gearboxes.
