NACHI - NN3010KW33

Details

Double-row cylindrical roller bearings are ideal for bearings with large radial loads. Because standard versions (NN and NNU) cannot transmit axial force, they are suitable for placing on the shafts where it is necessary to compensate axial displacement caused, for example, by thermal expansion of the shaft. We produce bearings with a cylindrical or tapered bore. For higher speeds, we recommend to use bearing with higher accuracy. Commonly used in lathes, machining centers, printing machines, and otherapplications where high radial loads and high-speed performance are required. Features are : Increased number of rollers to achieve higher rigidity. Oil groove and oil hole in the center of outer ring are also available. Both the NN3000 Series and NNU4900 Series are provided with brass alloy roller guide cage as standard. NN : Multi-row cylindrical roller bearing (ribbed inner ring, non-ribbed outer ring). K : T apered bore, W33 : With outer ring oil groove and oil hole.
