What are the exact dimensions of this SKF cylindrical roller bearing?

The bearing has a 55 mm bore diameter, a 120 mm outside diameter, and a 43 mm width.

What axial displacement does the NU design allow?

Because the inner ring has no flanges, the bearing accommodates axial displacement in both directions.

What cage material is used in this bearing?

The ECP designation indicates a glass-fibre reinforced polyamide (plastic) cage.

What radial internal clearance does this model have?

This bearing features standard normal radial internal clearance (CN class).

Is this cylindrical roller bearing sealed?

No, this is an open bearing without seals, intended for external oil or grease lubrication.

High radial capacity with Skf

Practical benefits

High radial load support: You handle heavy radial loads effortlessly thanks to the robust single-row roller geometry.
Quick and easy mounting: The separable design allows you to mount the inner and outer rings independently with ease.
Seamless axial displacement: You accommodate thermal shaft expansion smoothly during operation through the flangeless inner ring design.

In a nutshell

The right choise for

With the Skf nu 2311 ecp cylindrical roller bearing, you ensure reliable operation under heavy radial loads and high rotational speeds. Featuring dimensions of 55 x 120 x 43 mm and a single-row design, this bearing delivers high radial load capacity for electric motors, gearboxes, and pumps. The nu design with a flangeless inner ring smoothly accommodates axial thermal shaft expansion in both directions, preventing shaft binding in demanding assemblies. Its lightweight glass-fibre reinforced polyamide cage minimizes friction and operating noise. In addition, the separable construction lets you mount and maintain the inner and outer rings independently with ease.

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.
