ARB Cylindrical Roller Bearings Guide
Product Description
The American Roller Bearing NP288 cylindrical roller bearing consists of a double-ribbed inner ring, an outer ring with one integral rib and one loose flange ring, cylindrical rollers, and a cage. Its line-contact roller design provides high radial load capacity and rigidity, while the rib arrangement provides axial location and supports axial loads in both directions. The separable construction facilitates mounting and maintenance while providing stable performance under demanding loads. It is suitable for electric motors, industrial gearboxes, conveyors, mining equipment, crushers, and other heavy-duty machinery requiring reliable radial support and bidirectional axial location.
