The NUP Series cylindrical roller bearings feature an inner ring with an integral rib and a loose rib, providing axial location in both directions. This robust design combines high radial capacity with bidirectional axial guidance, making them the preferred choice for axle boxes, crane wheels, and heavy machinery requiring precise shaft positioning under combined loads.
