Heavy radial load capacity in motion

Practical benefits

High radial load capacity: You handle heavy radial loads at high speeds effortlessly thanks to the robust cylindrical rollers.
Easy and quick mounting: You install inner and outer rings separately thanks to the separable Skf bearing design.
Smooth low-friction operation: You benefit from reduced friction and quiet performance due to the durable polyamide cage.

In a nutshell

The right choise for

With the Skf nu 2308 ecp cylindrical roller bearing, you achieve reliable performance under heavy radial loads and high rotational speeds in industrial gearboxes, electric motors, and pumps. Featuring a single-row nu design with two integral flanges on the outer ring and a flangeless inner ring, it easily accommodates thermal expansion and axial displacement. Its separable design with dimensions of 40 x 90 x 33 mm allows you to mount and maintain the inner and outer rings separately with ease. In addition, the durable polyamide cage ensures low-friction, quiet operation and extended service life to keep your machinery running smoothly.

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.
