The ultra-precision double row cylindrical roller bearings of the NN series offer a unique balance between load carrying capacity, stiffness and speed. With three retaining edges on the inner ring and no retaining edges on the outer ring, the bearings allow axial displacement in both directions. The separable design simplifies mounting and dismounting and is particularly suitable for applications where load conditions require an interference fit on both the inner and outer rings.

• High radial load carrying capacity
• High stiffness and running accuracy
• Minimised noise, vibration and heat generation
• Can withstand bi-directional axial displacement
• Supplementary lubrication
