Cylindrical Roller Bearings are precision Bearings consisting of cages, rollers, and guide rings that can be separated from another bearing ring and are separable Bearings. Cylindrical Roller Bearings are easy to install and disassemble. Compared with other Bearings of the same shape and size, Cylindrical Roller Bearings have the characteristics of high load, low noise and high speed, suitable for high speed rotation.

Cylindrical Roller Bearings, like other types of Bearings, are divided into different categories, and how to select the type has been the most frequently asked questions. To learn more about Cylindrical Roller Bearings, let's take a look at the categories and features of Cylindrical Roller Bearings.

Single-column Cylindrical Roller Bearings with cages.

In single-row cylindrical roller bearings, the rollers are usually guided by a flange on one of the rings of a set of bearings, which is combined with specially designed and surface-treated roller ends, provides improved lubrication, reduced friction, and consequently lower bearing operating temperature.

Single-row Cylindrical Roller Bearings withstand heavy radial loads and high speeds. These bearings are manufactured in several different designs, the main difference being the retaining structure. The most common are NU, NJ, NUP, and N designs.

N type, outer ring without flanges, inner ring without flanges, can allow the shaft relative to the housing in both directions in the axial displacement. Therefore, these bearings are used as non-fixed end bearings.

NU type, outer ring double side, inner ring without side, the rest is the same as above.

NJ type, double rib on outer ring, single rib on inner ring. Therefore, these bearings are suitable for axial positioning of the shaft in one direction.

NF type, single flange on outer ring, double flange on inner ring, same as above.

NUP type, double baffle on Outer Ring, single baffle on inner ring and detachable baffle ring. These bearings can be used as positioning end bearings to provide axial positioning of the shaft in both directions.

NFP type, outer ring single baffle and detachable baffle ring, inner ring single baffle, the rest is the same as above.

Double-column Cylindrical Roller Bearings with cages.

Double-row Cylindrical Roller Bearings are compact, load-bearing and rigid. Therefore these bearings are mainly used in machine tools, rolling mills, rollers, grinders and large gearboxes.

NNU design and NN design double row Cylindrical Roller Bearings for detachable Bearings, I. E. Roller and cage assemblies can be mounted separately from other bearing rings, or all bearing parts can be mounted separately. These bearings are easy to install, inspect and maintain.

Double-row Cylindrical Roller Bearings have Cylindrical and tapered holes; Bearings with tapered holes allow for minor internal clearance adjustments and simplify positioning device construction.

Cylindrical Roller Bearings.

Cylindrical Roller Bearings are designed to withstand larger loads in single-row and double-row configurations. These Bearings are suitable for use in medium and low-speed locations with larger loads, such as construction machinery, vehicles, and steel, lifting machinery, etc. .

Single-row full load: NCF and NJG two kinds of structure, can withstand larger radial load and one side axial load.

Double-row full-load: NNC, NNCF, NNCL, NNF and other structures, can be used as axial positioning or non-positioning bearings.

Four columns of Cylindrical Roller Bearings.

Four-row Cylindrical Roller Bearings are used primarily for rolling mill necks to withstand heavy loads. Such bearings are usually made of surface hardened carburized steel to improve wear resistance and resistance to impact loads, and cages are usually machined steel cages or column-chipped cages.
