Double row cylindrical bearings for heavy radial loads
NN / NNU series
High-precision double row cylindrical roller bearings are available in the NN and NNU designs. These bearings feature a low cross sectional height, high load carrying capacity, high rigidity and high-speed capability. They are particularly well suited for machine tool spindles where the bearing arrangement must accommodate heavy radial loads and high speeds, while providing a high degree of stiffness.
