Physical Characteristics:
Cylindrical roller bearings can be divided into single row, double row and four row.



This kind of bearing may bear high radial load and certain axial load.



The rolling elements of cylindrical roller bearings are cylindrical, and both ends of the outer line have a correct slope, which can reduce and eliminate contact stress.



Cylindrical roller bearings designed by NN and NNU have high rigidity and are very suitable for milling and other machinery
