What are the dimensions of this bearing?

The bearing has an inside diameter of 80 mm, an outside diameter of 170 mm, and a width of 39 mm.

What does the C3 designation indicate?

C3 indicates radial internal clearance greater than normal, suitable for higher operating temperatures or thermal expansion.

What material is the bearing cage made of?

This bearing features a glass-fibre reinforced polyamide cage (plastic), designated by the P suffix.

Can an NU design bearing support axial loads?

No, the NU design has two flanges on the outer ring and none on the inner ring, supporting pure radial loads only.

Is this cylindrical roller bearing sealed?

No, it is an open bearing without built-in seals and requires appropriate external lubrication.

Smooth operation with Skf NU 316 ECP/C3

Practical benefits

High radial load capacity: You reliably manage heavy radial loads at high operational speeds thanks to the optimized internal geometry.
Quick and easy mounting: The separable bearing design simplifies installation, component replacement, and maintenance routines on your machinery.
Accommodates thermal expansion: It permits smooth axial displacement in both directions to prevent stress from shaft expansion during operation.

In a nutshell

The right choise for

With the Skf nu 316 ECP/C3 single row cylindrical roller bearing, you reliably handle heavy radial loads in electric motors, gearboxes, and industrial pumps. Thanks to its C3 radial internal clearance and lightweight glass-fibre reinforced polyamide cage, it ensures smooth and quiet operation at high speeds and elevated temperatures. The nu design allows smooth axial displacement in both directions to accommodate thermal shaft expansion. Additionally, the separable construction makes mounting, dismounting, and machine maintenance fast and straightforward.

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.
