Reliable Skf roller bearings for heavy radial loads

Practical benefits

High radial load capacity: The cylindrical roller geometry distributes heavy radial loads evenly, ensuring your machinery runs smoothly under demanding industrial conditions.
Low friction smooth running: Fitted with a lightweight polyamide cage, you benefit from reduced friction, lower operating temperatures, and extended component life.
Simplified mounting and maintenance: The separable NU design allows you to install inner and outer rings independently, making assembly and machine servicing effortless.

In a nutshell

The right choise for

With the Skf nu 307 ecp single-row cylindrical roller bearing, you ensure smooth and reliable operation for machinery under heavy radial loads. Measuring 35 x 80 x 21 mm, this open bearing is an ideal solution for electric motors, pumps, compressors, and industrial gearboxes. The nu design features two flanges on the outer ring, allowing the bearing to accommodate axial displacement and thermal shaft expansion with ease. Its lightweight glass-fibre reinforced polyamide cage significantly reduces friction and heat build-up, promoting quiet running and extended service life. In addition, the separable construction with normal radial internal clearance makes mounting, inspection, and maintenance straightforward.

Product description

Single row cylindrical roller bearings are designed to accommodate high radial loads in combination with high speeds. Having two integral flanges on the outer ring and no flanges on the inner ring, NU design bearings can accommodate axial displacement in both directions. An important feature is the separable design, which facilitates mounting and enables the bearing components to be interchanged.
