High Quality Cylindrical Roller Bearing Single Row Bearing

The main characteristics of cylindrical roller bearings are as follows:

1. High radial load capacity

Due to the linear contact between the rollers and raceways, this design enables the bearing to withstand heavy radial loads, making it suitable for applications involving heavy-duty loads and impact forces.

2. Low friction coefficient for high-speed operation

Cylindrical roller bearings exhibit minimal frictional resistance, allowing them to operate efficiently at high speeds. Their limiting speed is comparable to that of deep groove ball bearings, making them ideal for high-speed applications.

3. Separable inner and outer rings

The separable design of the inner and outer rings simplifies bearing installation and disassembly, facilitating convenient replacement or maintenance during later-stage servicing.

4. Capable of withstanding large radial loads (supplementary clarification)

While cylindrical roller bearings are primarily designed to carry radial loads, specific types—such as those with a single inner ring rib and flat retaining ring—can also accommodate smaller bidirectional axial loads.

Details Images

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 model of between both sides of inner ring. It can make shaft
relative bearing between the axial displacement generated in both directions.
