High radial load capacity for industrial applications

Practical benefits

High radial load rating: The robust cylindrical roller design allows you to handle heavy radial forces smoothly across demanding machinery.
Smooth operation with Skf: The lightweight polyamide cage minimizes friction and heat, ensuring you maintain quiet running performance at high speeds.
Quick and separable assembly: The separable ring design lets you mount and dismount inner and outer components independently on shafts with ease.

In a nutshell

The right choise for

With the Skf nu 311 ecp single row cylindrical roller bearing, you handle heavy radial loads smoothly across demanding industrial machinery, gearboxes, and electric motors. Featuring the nu design with dimensions of 55 x 120 x 29 mm, it easily accommodates axial shaft displacement without creating extra friction. The lightweight polyamide cage significantly reduces friction and vibration, giving you quiet, dependable operation at high rotational speeds. Because the inner and outer rings of this open bearing are separable, you can mount and dismount components independently, saving valuable time during installation and maintenance tasks.

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.
