Robust performance under heavy radial loads

Practical benefits

High radial load capacity: You reliably handle heavy radial forces and high operating speeds with the optimized internal geometry of Skf.
Separable design for mounting: You can mount the inner and outer rings independently, making installation and routine maintenance straightforward.
Accommodates thermal expansion: The flangeless inner ring design allows you to absorb axial shaft displacement in both directions smoothly.

In a nutshell

The right choise for

With the Skf nu 307 ecj single row cylindrical roller bearing, you reliably support heavy radial loads across industrial machinery, gearboxes, and electric motors. Thanks to the flangeless inner ring of the nu design, it accommodates axial thermal expansion of the shaft in both directions, eliminating mechanical stress. The robust sheet metal cage guides the cylindrical rollers smoothly to deliver dependable performance under demanding operating conditions. Its separable design allows you to mount the inner and outer rings independently, making installation and routine maintenance straightforward. Measuring 35 x 80 x 21 mm with standard cn radial internal clearance, this open bearing provides a stable, long-lasting solution for your floating bearing arrangements.

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.
