High radial capacity with Skf

Practical benefits

Heavy radial load support: You handle demanding radial forces effortlessly thanks to the robust cylindrical roller geometry.
Quick and easy mounting: The separable ring design lets you mount and service inner and outer rings independently.
Smooth axial displacement: The NU configuration accommodates thermal shaft expansion in both directions without creating internal stress.

In a nutshell

The right choise for

With the Skf nu 308 ecp single row cylindrical roller bearing, you achieve dependable and robust shaft guidance in demanding industrial applications such as electric motors, pumps, and gearboxes. Its optimized cylindrical roller geometry effortlessly accommodates heavy radial loads at high rotational speeds. The glass fibre reinforced polyamide cage minimizes operational friction and heat build-up during continuous duty. Furthermore, the nu design allows smooth axial displacement in both directions to absorb thermal shaft expansion without causing internal stress or binding. Thanks to the separable construction, you can mount and service the inner and outer rings independently for quick, accurate installation.

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.
