Super-precision double row cylindrical roller bearings are produced by HRT as standard in the NN design and NNU design.

nn design bearings can provide a unique balance between load carrying capacity, rigidity and speed and are therefore typically used as the drive end bearing in machine tool spindles.

nnu design bearings, with a very low cross sectional height, provide a higher degree of stiffness than bearings in the nn 30 series. however, nn 30 series bearings can accommodate heavier loads.
