NU328-E-XL-M1

The NU328-E-XL-M1 stands out as a high-capacity, single-row cylindrical roller bearing engineered for demanding industrial environments. As part of the X-life series, this bearing features optimized raceway surfaces and internal geometry that significantly boost its dynamic load rating to approximately 790 kN. The "E" designation indicates an enhanced internal design for maximum load-carrying capability, while the "M1" suffix identifies its robust, two-piece machined brass cage. This roller-guided cage construction is particularly effective in high-vibration applications or where rapid accelerations are common, ensuring stable performance across a wide temperature range from −30°C up to +150°C.

With its 140 mm bore and 300 mm outside diameter, the NU328-E-XL-M1 is designed as a non-locating bearing, allowing for axial displacement of the shaft relative to the housing in both directions. The outer ring is equipped with two integral ribs, whereas the inner ring has no ribs, facilitating a separable design that simplifies mounting and dismounting procedures. This modularity is a key advantage for maintenance teams working with heavy machinery, gearboxes, or large electric motors. By combining the precision of FAG/Schaeffler engineering with the durability of a solid brass cage, this bearing offers an extended service life and reduced frictional heat, making it a cost-effective solution for heavy-duty radial load requirements.
