Rollway Cylindrical Roller Bearings Guide
Product Description
The Rollway NJ311E Cylindrical Radial Roller Bearing features a separable inner ring with one flange, an outer ring with two flanges, crowned cylindrical rollers, and a precision-engineered retainer. Made from through-hardened bearing-grade steel, its precision-ground raceways and crowned rollers provide high radial load capacity and help reduce edge stresses. The design allows axial displacement in one direction while providing axial location and supporting light thrust loads in the opposite direction. The NJ311E bearing is suitable for industrial gearboxes, pumps, and heavy-duty machinery requiring reliable radial support and controlled axial movement, meeting the demanding needs of the United States industrial market.
