NU318 Cylindrical roller bearing 90x190x43mm

The NU318 is a single-row cylindrical roller bearing with a 90mm bore diameter, 190mm outside diameter, and 43mm width. This NU-series design features a separable inner ring with two integral flanges and a flanged outer ring, allowing free axial displacement of the shaft relative to the housing to accommodate thermal expansion.

Cylindrical roller bearings are used in applications requiring high radial load capacity, such as electric motors, gearboxes, machine tool spindles, and industrial pumps. The line contact between rollers and raceways provides excellent load distribution and permits high operating speeds with minimal friction.
