What are the dimensions of this SKF cylindrical roller bearing?

This bearing features an inside diameter of 65 mm, an outside diameter of 140 mm, and a width of 33 mm.

What does the C3 designation indicate?

C3 denotes a radial internal clearance greater than normal, compensating for thermal expansion or heavy interference fits during operation.

Can the NU design accommodate axial displacement?

Yes, with two integral flanges on the outer ring and no flanges on the inner ring, it accommodates axial displacement in both directions.

What material is used for the cage?

The cage of the NU 313 ECP/C3 is made of reinforced polyamide (polymer/plastic).

Does this bearing come sealed?

No, it is an open bearing without seals, designed for external lubrication inside a protected housing.

Robust support with Skf

Practical benefits

High radial load capacity: You handle heavy radial loads smoothly across high-speed industrial machinery and demanding drive systems.
Accommodates axial thermal expansion: The flangeless inner ring design allows effortless axial displacement during operational shaft expansion.
Fast and separable mounting: You simplify routine maintenance and installation because the separable components mount individually with ease.

In a nutshell

The right choise for

With the Skf nu 313 ECP/C3 single row cylindrical roller bearing, you reliably handle heavy radial loads at high operating speeds in demanding machinery, electric motors, and gearboxes. Its separable nu design smoothly accommodates axial shaft expansion caused by temperature variations, preventing unwanted stress. The increased C3 internal clearance prevents binding during tight interference fits and thermal fluctuations. Featuring a lightweight polymer cage and a separable inner ring, installation and routine maintenance are fast and efficient. With dimensions of 65 x 140 x 33 mm, this unsealed bearing delivers the dependable performance you need for non-locating bearing positions.
