Description:
NN and NNU type double row cylindrical roller bearings are compact structure,which with strong rigidity and bears load capacity.Even if it has bear heavily load ,its deformation is small.It mostly used for machine tool spindle bearing.
FC,FCD,FDCP-type four-row cylindrical roller bearings can bear greater radial load,mostly using for rolling mill and other heavy machinery.
