The NU328-C4 is a single row cylindrical roller bearing with a 140mm bore diameter, 300mm outside diameter, and 62mm width. The NU design features a separable inner ring with fixed outer ring ribs, allowing for free axial displacement of the shaft relative to the housing. The C4 radial clearance designation provides greater internal clearance than standard, accommodating thermal expansion and misalignment conditions.
Cylindrical roller bearings are widely used in heavy-duty applications requiring high radial load capacity, including electric motors, gearboxes, industrial pumps, and machine tool spindles. This bearing size is typically found in large rotating equipment such as crushers, mills, and heavy industrial machinery where precise radial guidance and high load capacity are essential.
