For pulley and transmission setups that see heavy radial forces, the IKO NAS UUNR series of cylindrical roller bearings is a common choice. These bearings pair cylindrical rollers with built-in sealing, so they handle environments where dust or moisture is present. MR Industrial Accessories LLC supplies them to customers throughout the United States and Latin America, and our team can help you match the right size to your equipment.

The part number itself tells you a lot. The letters NAS mark this as a cylindrical roller bearing intended for pulley mounting. The four-digit number that follows, as in NAS 5008UUNR or NAS 5012UUNR, sets the bore and the main dimensions. The UUNR suffix points to double-lip sealing and a design tailored to pulley use. Every reference, such as NAS 5010UUNR, is a standardized size, which simplifies finding a replacement.

You will find these bearings in agricultural machinery pulleys, conveyors, lifting gear and belt drive systems. They also show up in tensioner and idler pulleys on production lines. In those spots, radial loads run high and the air may carry dust or moisture. The sealed construction keeps lubricant in and particles out, which helps the bearing last under tough conditions.

Choosing the correct bearing starts with the shaft diameter, the radial load and the working environment. The UUNR seal makes sense when contaminants are a concern. Check that the pulley housing is clean and free of burrs before you begin. When mounting, press evenly on the ring being fitted and never strike the rollers directly. Use the lubricant specified by the manufacturer, and make sure shafts are aligned to prevent unwanted axial loads.

For a replacement, you can cross-reference the IKO number with other brands that make cylindrical roller bearings for pulleys. Standard dimensions often line up, but always confirm the sealing type and load capacity. If you have the original part number or the shaft and housing measurements, we can point you to a compatible alternative. The IKO NAS UUNR series is a well-known reference in the market.
