ARB Cylindrical Roller Bearings Guide
Product Description
The American Roller Bearing NJ18/630 cylindrical roller bearing consists of a double-ribbed outer ring, a single-ribbed inner ring, cylindrical rollers, and a cage. Its line-contact roller design provides high radial load capacity and rigidity, while the rib arrangement enables axial location and supports axial loads in one direction. 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 axial location.
