Reliable operation with Skf

Practical benefits

High radial load capacity: Thanks to the cylindrical rollers, you handle heavy radial loads smoothly during demanding high-speed operations.
Smooth axial displacement: The NU design accommodates axial expansion in both directions, so you easily compensate for shaft length variations.
Quick and separable mounting: With the separable inner and outer rings, you mount and inspect each bearing component with ease.

In a nutshell

The right choise for

With the Skf nu 310 ecp single-row cylindrical roller bearing, you ensure reliable and smooth operation in demanding machinery such as electric motors, gearboxes, and pumps. Its cylindrical rollers effortlessly handle heavy radial loads. The nu design accommodates axial displacement in both directions, reliably absorbing thermal shaft expansion and preventing mechanical binding. Engineered with a glass-fibre reinforced polyamide cage, it reduces friction during high-speed operations. Additionally, the separable design makes mounting, inspection, and maintenance of the inner and outer rings quick and 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.
