Four-row cylindrical roller bearings are designed to accommodate very heavy radial loads in combination with medium to high speeds. The SKF assortment includes many designs and variants, such as bearings with a cage and full complement bearings. Depending on the configuration of the outer and inner rings, the bearings are available in locating as well as non-locating designs.
