NU230-E-XL-M1

The NU230-E-XL-M1 is a single-row cylindrical roller bearing engineered for high radial load capacity and superior speed capability. Designated with the NU prefix, this bearing features two fixed ribs on the outer ring and a smooth inner ring, making it a non-locating, or "floating," bearing. This crucial design characteristic allows the inner ring to shift axially relative to the outer ring in both directions, making it an ideal choice for machinery where shaft thermal expansion is a factor, such as large industrial transmissions, pumps, and metal rolling equipment. Its separable components also simplify installation and maintenance, offering practical advantages during assembly and repair.

Key technical enhancements are encapsulated in its suffixes. The E and XL notations signify an "Increased Capacity" or "X-Life" design, meaning the bearing incorporates more or larger rollers to significantly boost the dynamic load rating, which sits at an impressive 520 kN. The M1 designates a two-piece, roller-guided solid brass cage, which provides exceptional strength and guidance for the rollers, enabling the bearing to achieve high limiting speeds (4,550 r/min) while maintaining stability and low friction. With dimensions of a 150 mm bore, 270 mm outer diameter, and 45 mm width, the NU230-E-XL-M1 provides a robust, high-performance solution for demanding applications requiring both radial strength and axial freedom.
