ARB Cylindrical Roller Bearings Guide
Product Description
The American Roller Bearing NNU4948 double-row cylindrical roller bearing consists of an outer ring, a separable inner ring, two rows of cylindrical rollers, and a machined brass cage. Its double-row design provides high radial load capacity and rigidity, while allowing axial displacement to accommodate shaft expansion during operation. The separable construction facilitates mounting and maintenance, while the robust cage and roller arrangement ensure stable performance under demanding loads. It is suitable for machine tool spindles, industrial gearboxes, pinion stands, rolling mill equipment, printing machinery, and other heavy-duty rotating equipment requiring high radial load capacity, rigidity, and reliable shaft support.
