NNU 4926 B/SPW33
Super-precision double row cylindrical roller bearing with lubrication feature
Super-precision double row cylindrical roller bearings in the NNU 49 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
Lubrication feature
Thin section enabling compact application design
