The NN 30 Series double row cylindrical roller bearings provide a good balance between load capacity, stiffness, and speed. These bearings have three flanges on the inner ring and no flanges on the outer ring. This allows the bearings to handle axial movement of the shaft in both directions. The separable design makes it easier to install and remove the bearings, especially when both rings need to have an interference fit to handle the loads. The tapered bore also helps with setting the right amount of clearance or preload when putting the bearings in.
