Since the rollers of cylindrical roller bearings make the line
contact with the raceways, these bearings can support heavy radial loads and are suitable for high-speed operation.
Cylindrical roller bearing
come in various configurations.
The roller is guided by the collars of either the inner or outer ring.
Since NU and N-Type bearings are not provided with a collar on the inner and outer ring. The inner and outer rings can flow axially relative to the other under an axial load. These bearings are most
suitable for use on the free side of the shaft.
Bearing type NJ, NUP, and NF have collar rings on both
inner and outer rings and can receive a certain amount of axial load.
These bearing types are sometimes used on the fixed side of the shafts.
Since cylindrical roller bearing are separable, they can easily be mounted or dismounted, in the case when interference fits are
required.
The boundary dimensions of type E cylindrical roller bearings
are the same as those of the standard type. The load capacity of type E
bearing is increased by enlarging the roller diameter, increasing roller
length, and increasing the number of rollers. The bearings are
classified by attaching the suffix ‘’E’’ at end of the basic number.
