Superior spindle stability with Skf

Practical benefits

High radial load capacity: The double row roller layout enables you to support demanding radial loads with unmatched structural rigidity.
Smooth and quiet operation: A durable polyamide cage reduces friction and heat build-up, ensuring you achieve optimal precision during continuous machining.
Fast and simple installation: With its separable ring configuration and cylindrical bore, you complete mounting and maintenance procedures with absolute ease.

In a nutshell

The right choise for

Achieve maximum spindle rigidity and rotational accuracy with the Skf nn 3011 TN/SP double row super-precision cylindrical roller bearing. Its double row roller layout effortlessly handles heavy radial loads and eliminates shaft deflection during demanding machining tasks. The lightweight polyamide cage minimizes friction, vibrations, and heat generation at high operating speeds. Featuring a 55 mm cylindrical bore, a 90 mm outside diameter, a 26 mm width, and C1 radial internal clearance, this open bearing accommodates axial displacement in both directions. This separable design simplifies mounting and ensures smooth, highly reliable operation.

Product description

Super-precision double row cylindrical roller bearings in the NN 30 series provide a unique balance between load carrying capacity, rigidity and speed. Having three flanges on the inner ring and no flanges on the outer ring, the bearings can accommodate axial displacement in both directions. The separable design simplifies mounting and dismounting, particularly when load conditions require both rings to have an interference fit.

Very high radial load carrying capacity
High rigidity and high running accuracy
Minimize noise, vibration and heat generation
Accommodate axial displacement in both directions
