Instruction of Cylindrical Roller Bearing:

1. Single Row and Double Row Cylindrical Roller Bearings:

Cylindrical roller bearings is a kind of detachable bearings, it is easy to install and tear down. It's advantage is much more obvious especially under the demands of outside ring and inside ring, the excess coupling between bearing and the hole in outside shell. The amendment contact between balls and rollaway nest reduced the pressure in fring. Meanwhile, compare to similar ball bearing, it can also stand much more radial load, what's more, some type of cylindrical roller bearing even can suffer from some axial load.

2. Four Row Cylindrical Roller Bearings

This kind of bearings has four row cylindrical rollers, with a good radial load capacity. However, it cannot collet strength along axis. Moreover, it can be installed with inside ring and outside ring parts ( with whole set of rolling and retainer ) separately. This kind of bearing includes following 3 types: FC type, FCD type and FCDP type. It mainly used in working roll and supporting roll of these machine, such as cold and hot rolling mill and so on.

Dawson offer various types of cylindrical roller bearings, which can be used in different occasions.

And Cylindrical Roller Bearing have NU, NJ and N type, the following is the description of difference between these type:

N designThe inner ring has two integral flanges and the outer ring is without flanges. Axial displacement of the shaft with respect to the housing can be accommodated in both directions within the bearing itself. The bearings are therefore used as non-locating bearings.

NU designThe outer ring of bearings of the NU design has two integral flanges and the inner ring is without flanges. Axial displacement of the shaft with respect to the housing can be accommodated in both directions within the bearing itself.

NJ designThe outer ring has two integral flanges and the inner ring one integral flange. The bearings are therefore suitable for the axial location of a shaft in one direction.
