NTN Cylindrical roller bearing NU

Since the rolling element is a roller, the load capacity is large, and the roller is guided by the inner ring or the brim of the outer ring.
Since the inner ring and outer ring can be separated, it is easy to assemble, and both can be fitted tightly.
In addition, since either the inner ring or the outer ring moves freely in the axial direction when there is no brim, it is ideal for use as a so-called free side bearing that absorbs the elongation of the shaft.
On the other hand, the brim type can receive a slight axial load between the roller end face and the brim.
There are also HT type bearings that take into consideration the shape of the brim and roller end face to increase the axial load capacity, and E type cylindrical roller bearings that have been devised for internal design to increase the radial load capacity. E type is standard for small diameter size.
