Double row Cylindrical roller bearings

Double Row Cylindrical Roller Bearings 

There are two kinds of structures of double row cylindrical roller bearings: cylindrical inner holes and conical inner hole. This kind of bearing has the advantages of compact structure, high rigidity, large load capacity and small deformation after loading, etc. It is especially suitable for machine tool spindle support. It can be divided into two types: NN series and NNU series. NN series cylindrical roller bearing has double flange on the inner ring, but no flange on the outer ring. NNU type bearing has double flange on the outer ring but with no flange on the inner ring. Both bearings do not limit the relative axial displacement between the shaft and the housing and can be used as non-positioning bearings.
