NU2230-E-XL-M1

The NU2230-E-XL-M1 Cylindrical Roller Bearing is a high-performance, single-row unit specifically engineered for demanding industrial applications. Featuring a robust design with dimensions of 150 mm inner diameter, 270 mm outer diameter, and 73 mm width, this bearing excels in supporting high radial loads. The -E suffix denotes an Increased Load Capacity design, utilizing a modified internal geometry to accommodate greater forces, while the -XL designation indicates an X-life product, guaranteeing superior performance and a longer service life compared to standard cylindrical roller bearings. Its separable components, including a solid inner and outer ring, simplify installation and maintenance procedures, making it a reliable choice for critical equipment.

The design configuration of the NU2230-E-XL-M1 makes it ideal for use as a non-locating (floating) bearing. This is achieved by the outer ring having two rigid ribs and the inner ring being smooth (Type NU), allowing for axial displacement of the shaft relative to the housing. This crucial feature prevents stress from thermal expansion or shaft deflection. Furthermore, the -M1 suffix highlights the inclusion of a two-piece, roller-guided solid brass cage, which provides excellent stability and minimal friction, even at the high limiting speed of 4,550 rpm. Its exceptional load ratings (Basic Dynamic Load Rating: 780,000 N, Basic Static Load Rating: 970,000 N) make it the perfect solution for heavy machinery, including gearboxes, large electric motors, and industrial pumps.
