SKF NNF series bearings are double row cylindrical roller bearings with a sealed design, built for high radial loads. They suit gearboxes, machine tools and mining equipment where load capacity and rigidity matter. MR Industrial Accessories supplies this line and helps you select the right variant for your application.

The part number breaks down into blocks. The NNF prefix identifies the double row cylindrical roller series with flanges on the inner ring. In a designation such as NNF 5016, the first two digits (50) give the dimension series and the last two (16) give the bore in millimeters. ADA denotes a cylindrical bore with a retaining ring groove, and 2LSV means a double low-friction contact seal. So NNF 5026 ADA-2LSV combines all these features in one code.

These bearings are selected where radial loads are high and speeds are moderate. They appear in gear reducers, conveyor belts, mills, presses and earthmoving equipment, as well as machine tool spindles and support rollers of large structures. The double row and integrated seals make them suitable for dusty or humid environments when the specified mounting and lubrication are followed.

Selection depends on the radial and axial loads, the rotation speed and the operating environment. The NNF series handles significant radial loads and some axial load in one direction. The 2LSV seal keeps contaminants out and lubricant in, but check that the working temperature suits the seal material. During mounting, align the housing and shaft carefully and avoid impacts that could damage rollers or raceways. Correct lubrication extends service life.

When replacing a bearing, equivalents between brands are common. The SKF NNF series may have counterparts from other manufacturers with similar designations, but suffixes and tolerances do not always match. The safest approach is to compare the main dimensions (bore, outer diameter and width) and the load conditions.
