Single-row Cylindrical Roller Bearing
Single-row Cylindrical Roller Bearing
Detail

NU type, N type:

Nu type: the outer ring with double ribs, the outer ring, rollers and cage can be separated from the inner ring.

N type: the inner ring with double ribs, the inner ring, rollers and cage can be separated from the outer ring.

NU type and N type allow the axial displacement of shaft and housing within a range, this displacement may be caused by thermal expansion or installment error. This kind of bearing can be used for free end bearing, can not limit the axial displacement of shaft and housing, but can only carry the radial load.

NJ type and NF type

NJ type: the outer ring with double ribs, the inner ring with one rib.

NF type: the inner ring with double ribs, the outer ring with one rib.  

NJ and NF can carry single direction axial  load.                                  

NUP type, NH type: 

NUP type: the out ring with double ribs, the inner ring with one rib and loose rib.

NH type: the outer ring with double ribs, the inner ring with single rib and slope end. Their inner and outer rings can be mounted separately (constituting of rollers and cage). Besides radial load, this type of bearings can carry small axial load in two directions if the displacement of shaft and housing are limited within the bearing axial clearnce. Thus they can be used on the fixed end of the shaft.

NCL...V type cylindrical roller bearings do not have ribs and cage, but they have double locking rings on the outer rings. This kind of the bearings without cage have many rollers. This type bearing can carry heavier radial load with lower limit rotation speed in comparing with other cylindrical roller bearings with the same dimensions. Their outer ring and inner ring are not separable, can not be mounted separately, but they can limit the axial displacement of the shaft and housing in two directions within bearing's axial clearance.

NB type: This type do not have ribs on inner or outer rings. There are lubricating holes on the outer ring. Their inner ring, outer ring and cage with rollers can be mounted separately . They can not limit the axial displacement of the shaft or housing and can not carry radial load.

NJ...V type: This type cylindrical roller bearings have single ribs on inner ring and without cage. Because of owning large number of rollers and without cage, this type bearing can carry heavier radial load with lower limit rotation speed in comparing with others cylindrical roller bearings with the same dimensions. They can not limit the axial displacement of the shaft or housing within bearing's axial clearance and unable to carry axial load.  

NCR...V type:  This type cylindrical roller bearings belong to spherical short cylindrical roller bearings without cage and have single rib on the outer ring.

This type bearing do not have cage and full of rollers, so they can carry heavier radial load with lower limit rotating speed with the same dimensions. They can limit the axial displacement of the shaft or housing in two directions within bearing's axial clearance.

...N type (with snap groove)

For some single-row cylindrical roller bearing, the outer ring with snap groove, the post code is "N". Position the bearing in the bearing block with snap ring in axial direction. Smplify the axial fastening in the hole of housing. The hole of housing can be through-hole, in order to reduce the axial dimension of parts.
