INShine N203 NJ203 Cylindrical Roller Bearing

The outer wall with both cylindrical roller bearings
NJ-cylindrical roller bearings, its outer wall to double, a single inner wall.
NF-cylindrical roller bearings, the outer ring of single-wall, double inner wall.
NJ and NF-cylindrical roller bearings, may limit the axis of the shell in one direction or the axial displacement, axial positioning the realization of a one-way, and less able to cope with its one-way axial load. 
 
Cylindrical roller bearings usually by a wall bearing rings of the two lead, Cage, and guide roller rings composed of a combination of things, the general type of bearing is detachable. Bearing this installation, the demolition of more convenient, especially when requested, and the outer shell and shaft are fit more shows its advantages. Bearing this kind generally used for radial load to bear, only, the outer wall with all the separate bearings can withstand axial loading smaller or larger batch of axial load. The same size and shape of the deep groove ball bearings , bearing with such a large radial load capacity of the structure from the point of view, also applies to high-speed rotation.
