IKO NAS UUNR series cylindrical roller bearings are components designed to withstand high radial loads in pulley and transmission applications. Their construction with cylindrical rollers and integrated sealing makes them suitable for environments with moderate contamination. At MR Accesorios Industriales we sell them for the Argentine market, with technical advice to select the correct size for your equipment.

The designation of this series combines letters and numbers that identify the type and size. NAS indicates that it is a cylindrical roller bearing for pulleys, with specific mounting characteristics. The four-digit number, as in NAS 5008UUNR or NAS 5012UUNR, defines the bore diameter and main dimensions. The UUNR suffixes indicate double-lip sealing and a special configuration for pulley applications. Each part number, for example NAS 5010UUNR, corresponds to a standardized size that facilitates interchangeability.

These bearings are used in pulleys of agricultural machinery, lifting equipment, conveyors and belt drive systems. In Argentine industry they appear in combine harvesters, seeders, cranes and road equipment, where radial loads are high and the environment may have dust or moisture. Their sealed design helps retain lubricant and exclude particles, extending service life under demanding conditions. They are also used in tensioner and idler pulleys on production lines.

To select the right bearing, take into account the shaft diameter, radial loads and environmental conditions. The UUNR sealing is appropriate when there is exposure to contaminants; verify that the pulley housing is clean and free of burrs. During mounting, apply uniform force on the ring being fitted and avoid direct blows on the rollers. Lubrication must be the one specified by the manufacturer and alignment between shafts is critical to avoid parasitic axial loads.

When looking for a replacement, you can cross-reference the IKO part number with other brands that offer cylindrical roller bearings for pulleys. Standardized dimensions usually match, but it is important to verify the type of sealing and the load capacity. If you have the original part number or the shaft and housing measurements, we will indicate the compatible alternative. The IKO NAS UUNR series is a reliable reference on the market.
