ARB Cylindrical Roller Bearings Guide
Product Description
The American Roller Bearing NN4964 double-row cylindrical roller bearing consists of an inner ring, a separable outer ring, two rows of cylindrical rollers, and a machined brass cage. Its double-row roller arrangement provides high radial load capacity and rigidity, while allowing axial displacement to accommodate shaft expansion during operation. The separable outer ring facilitates mounting and maintenance, while the robust cage and roller arrangement provide smooth and stable performance under demanding loads. It is suitable for lathes, machine tools, industrial gearboxes, pinion stands, rolling mill equipment, and other heavy-duty rotating machinery requiring high radial load capacity, rigidity, and reliable shaft support.
