NU2228-E-XL-M1

The NU2228-E-XL-M1 is a high-capacity, single-row cylindrical roller bearing engineered for demanding industrial applications. As a non-locating (floating) bearing, the NU design features two integral ribs on the outer ring and a rib-less inner ring. This configuration allows for axial displacement of the shaft relative to the housing, making it an essential component for installations where thermal expansion is a factor, such as large gearboxes, electric motors, pumps, and heavy-duty compressors. Key technical attributes include its metric dimensions (140 mm bore, 250 mm outer diameter, and 68 mm width) and an extra-light (XL) series design, which provides an outstanding balance of size and load-carrying capability.

This robust bearing features an optimized internal geometry, denoted by the 'E' for enhanced dynamic load rating, along with a precision-machined brass cage ('M1'). The brass cage is roller-guided, ensuring consistent roller spacing and superior performance at higher operating temperatures and speeds, offering a limiting speed of up to 4,900 rpm. The high-quality steel construction and advanced roller profile minimize stress concentration, contributing to the bearing's exceptional lifespan, stiffness, and ability to handle very high radial forces. The separable components of the NU2228-E-XL-M1 simplify both mounting and dismounting, streamlining maintenance procedures and reducing downtime in critical machinery.
