Product Description

 

Cylindrical roller bearings without ribs on the inner or outer ring, the inner and outer rings can move relative to the axial direction, so they can be used as free end bearings. Cylindrical roller bearings with double ribs on one side of the inner ring and outer ring and a single rib on the other side of the ring can withstand a certain degree of axial load in one direction. Generally, a steel stamping cage is used, or a copper alloy turning solid cage is used. However, there are also part of the use of polyamide forming cage.

N type:

The 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 type:

The 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 type:

The 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.

NF type:

The outer ring has one integral flange and the inner ring two integral flanges.

NUP type:

The outer ring has two integral flanges and the inner ring one integral flange and one non-integral flange in the form of a loose flange ring. The bearings can be used as locating bearings, i.e. they can provide axial location for a shaft in both directions.

RN type:

No outer ring and the inner ring two integral flanges.

NN type:

NN type bearing without ribs on outer ring,there is a wall in the midel of between both sides of inner ring. It can make shaft relative bearing between the axial displacement generated in both directions.

Product Parameters

single row cylindrical roller bearings
Single row cylindrical roller bearings, as free supporting, are usually matched with angular contact ball bearings which serve as fixed supporting. The most commonly used cylindrical roller bearings in the machine tool are double cylindrical roller bearing with tapered bore.  This kind of bearing can bear greater radial load with detachable inner and outer rings, and can not bear the axial load , so they are often used with double-direction angular contact thrust ball bearings which bear axial load.

four row cylindrical roller bearings

Four row cylindrical roller bearings can carry much heavier radial load and shock load. They have higher precision and can be applied in the equipment which runs with high rotational speed. Grinding the surface of raceway and roller at same time after the inner ring is pressed on roller neck, it favors the improvement of rolling precision and the free adjustment of mounting clearance of bearings. These bearings are mostly applied to the working roller and backup roller of rolling mills and some other cases.

FC: double outer rings, single inner ring, and inner without flange.

FCD: double outer rings, double inner rings, and inner ring without flange.

FCDP: double outer rings, only have center flange, but with loose rib, double inner ring, inner without flange.

double row cylindrical roller bearings

Double row cylindrical roller bearings with tapered bore are matched with tapered shaft neck of spindles. During the processes of bearing assembly, the axial movement of inner ring can swell the inner ring, and then the internal radial clearance can be changed and the bearing preload will be acheived. As for the N10 and NN30 series of cylindrical roller bearings, the inner ring has shoulder, the outer ring can be separated. For double row cylindrical roller bearings used with oil lubrication, a circumferential oil groove and three symmetric lubricant holes are set in the middle of outer ring, marked W33.
