What are the dimensions of this bearing?

The bearing has a 55 mm bore diameter, a 120 mm outer diameter, and a width of 29 mm.

What does the C3 clearance mean for this bearing?

C3 indicates a greater radial internal clearance than standard, suited for high speeds or thermal expansion.

Can this bearing accommodate axial displacement?

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

What material is the cage made of?

The cage is made of reinforced polyamide (polymer/plastic), reducing friction and weight.

Does this SKF bearing have integrated seals?

No, this is an open cylindrical roller bearing without seals and requires external lubrication.

Smooth operation under heavy loads

Practical benefits

High radial capacity: You handle heavy radial loads effortlessly thanks to the optimized cylindrical roller construction.
Simple separable assembly: The separable design of the Skf NU 311 ECP/C3 makes mounting and maintenance far more convenient.
Accommodates axial displacement: The flangeless inner ring allows you to smoothly absorb shaft expansion during high-temperature operation.

In a nutshell

The right choise for

With the Skf nu 311 ECP/C3 single row cylindrical roller bearing, you ensure reliable operation under heavy radial loads and high speeds. Featuring dimensions of 55 x 120 x 29 mm, this bearing provides increased C3 radial internal clearance to accommodate thermal shaft expansion without binding. The nu design, with two flanges on the outer ring and a flangeless inner ring, allows smooth axial displacement in both directions. Its lightweight reinforced polyamide cage reduces friction and ensures quiet running. In addition, the separable construction makes mounting and maintenance on electric motors, gearboxes, and industrial machinery fast and practical.

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.
