Cylindrical Roller Bearing – NU 306 ECM

The SKF NU 306 ECM cylindrical roller bearing is a high-quality, single-row bearing designed for heavy radial loads and high-speed applications. Its NU design features two fixed ribs on the outer ring and no ribs on the inner ring, allowing the shaft to move axially in both directions, which makes it ideal for applications requiring thermal expansion compensation. The ECM brass cage ensures durability, strength, and reliable roller guidance. With a compact size of 30 mm (bore) × 72 mm (outer diameter) × 19 mm (width) and a weight of about 0.41 kg, this bearing delivers excellent performance in demanding industrial environments such as pumps, motors, gearboxes, conveyors, and heavy machinery.
