Super-precision double row cylindrical roller bearings in the NNU series are designed to accommodate heavy radial loads and high speeds, while providing a high degree of stiffness. Having three flanges on the outer ring and no flanges on the inner 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.

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