NU308-C3 Cylindrical roller bearing 40x90x23mm C3

The NU308-C3 is a single-row cylindrical roller bearing with dimensions of 40mm bore, 90mm outside diameter, and 23mm width. This NU-type bearing features a separable design with an inner ring and roller cage assembly, while the outer ring has no flanges on one side, allowing for axial displacement to accommodate thermal expansion in the shaft assembly.

Cylindrical roller bearings are designed for applications requiring high radial load capacity and high-speed operation. Common applications include electric motors, gearboxes, machine tool spindles, pumps, and conveyor systems where radial loads dominate and axial freedom is beneficial.
