What are the dimensions of this cylindrical roller bearing?

This bearing has an inside diameter of 50 mm, an outside diameter of 110 mm, and a width of 27 mm.

What does the C3 designation indicate?

The C3 designation indicates a larger internal radial clearance than standard, suitable for higher operating temperatures or speeds.

Can this bearing accommodate axial displacement?

Yes, the NU design features two flanges on the outer ring and none on the inner ring, accommodating axial displacement in both directions.

What material is the cage made from?

The cage of this ECP version is made from glass fiber reinforced polyamide (plastic).

Is this SKF bearing sealed?

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

Heavy radial capacity from Skf

Practical benefits

High radial load rating: You handle heavy radial forces at high rotational speeds with robust cylindrical roller geometry.
Fast and separable mounting: You install the inner and outer rings independently thanks to the practical separable bearing design.
Increased C3 internal clearance: You compensate for thermal expansion and maintain smooth operation under demanding operating temperatures.

In a nutshell

The right choise for

With the Skf nu 310 ECP/C3 single-row cylindrical roller bearing, you ensure reliable power transmission under demanding industrial conditions. Engineered to handle high radial loads at high rotational speeds, it keeps your machinery operating smoothly. The increased C3 radial internal clearance prevents shaft binding caused by thermal expansion during high-temperature runs. Thanks to the separable nu design, you can mount the inner and outer rings independently, making installation and maintenance fast and straightforward. Its lightweight glass fiber reinforced polyamide cage minimizes friction and optimizes performance. It is the dependable solution for electric motors, industrial gearboxes, and pumps requiring seamless operation.

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.
