SKF bearings manufactures many types and sizes of cylindrical roller bearings. The majority bearing a row with cage. The roller bearings (sans cage) in one or two rows for general applications are also in the range of SKF standard. The bearings cage with a high load capacity radial and admit high speeds. Roller roller suitable for very high radial loads at moderate speeds.

The rolls are a key element within the cylindrical roller bearings SKF. Their geometry, also called logarithmic profile, ensure optimum allocation of constraints at the contact areas inside rotation. Their surface condition promotes the formation of a lubricant film and correct the rotation rolls. Compared with conventional designs, they provide a more reliable operation and are less sensitive to defects alignment.

The range of cylindrical roller bearings SKF includes executions following basic:

–  skf Single row cylindrical roller bearings in a row, with cage, mainly types NU, NJ, NUP and N
–  skf Double row cylindrical roller bearings in two rows, with cage, mainly types NNU and NN
–  skf Multi-row cylindrical roller bearings in several rows, with cage
–  skf Single row full complement cylindrical roller bearings in a row joined, mainly types NCF and NJG
–  skf Double row full complement cylindrical roller bearings joined by two rows, mainly type NNF
–  skf Multi-row full complement cylindrical roller bearings joined by several rows, four or eight rows of rollers

The full range SKF cylindrical roller bearings also includes:

– Cylindrical roller bearings in a row of high-precision, 100% steel or hybrid,
– Cylindrical roller bearings with two rows of high-precision, 100% steel or hybrid,
– Sets-bearings and cylindrical roller bearings for axle box rail
– Cylindrical roller bearings in a row for traction engines and railway applications,
– Cylindrical roller bearings several rows open or protected for rolling mills,
—Bearing materials for cold mills at six-cylinder,
– Combinations bearing thrust for continuous furnaces.

In a cylindrical roller skf bearing in a row, the rollers are always guided between the shoulders “open” fixed one of the rings. These shoulders “open”, combined with a design and a surface finish specific faces rolls, improve lubrication, while reducing friction and, therefore, the operating temperature.

The ring shoulders with fixed and all-cage cylindrical rollers may be separated from the other ring, which facilitates the installation and dismantling, particularly when the load conditions require a fit of the two rings.

The cylindrical roller bearings in a row SKF have a strong capacity for radial load and allow high speeds. They are made of several types that differ in configuration shoulders. The most common types are the UN, N, NJ and NUP.

The outer ring bearing type NU has two fixed shoulders, and their inner ring is without shoulder. The axial displacement of the tree compared to the level can be supported in both directions within the same rotation. The bearings are used as bearings free. For reasons of manufacturing and maintenance, it may be that both shoulders of the outer ring bearing large type NU designated by a number of design are not fixed but takes the form of rings free shoulder.

The inner ring has two shoulders fixed and the outer ring is without shoulder The axial displacement of the tree compared to the level can be supported in both directions within the same rotation. The bearings are used as bearings free.

The outer ring has two shoulders fixed and the inner ring a shoulder fixed These bearings therefore agree to the setting axial shaft in one direction.

The outer ring has two shoulders fixed and the inner ring a shoulder fixed and a ring shoulder free These bearings can be used as fixed landings, ie they can be used to establish a tree axially in both meaning.

The cylindrical roller skf bearings in two rows are distinguished by a small section, a large load capacity and high rigidity. They are mainly used in machine tools, rolling mills, grilles, shredders or grandparents reducers.

The cylindrical roller bearings with SKF two rows are mainly types NNU and NN The bearings are dismantled, whose ring shoulders fixed and the roller can be mounted separately from the other ring, or all of whose components can be mounted separately. The assembly, testing and maintenance of these bearings are simplified.

The cylindrical roller bearings in two rows are manufactured with a cylindrical or conical bore. Roller-type NN generally have a conical bore. The mounting bearing conical bore allows for a certain radial internal or pre-given.

These bearings, with the exception of bearings type NNUP permit within certain limits axial movement between the shaft and landing in the rotation itself.

The cylindrical roller bearings to four to six rows and rows (Fig. 2) are used almost exclusively for trunnions mill, grilles or roller presses. Their friction is lower than other roller bearings. Because normally fitted with fit on the trunnion cylinder, they are particularly suited to the mills where the speed is high.

Their low section authorizes diameters trunnion quite large compared to the diameter of the roller. These bearings have a capacity of charge due to the very large number of rolls they can contain.

The cylindrical roller skf bearings several rows not tolerate that radial loads. They are fitted with ball bearings or rigid contact oblique, or with tapered roller bearings radial or axial who can tolerate axial loads.

The cylindrical roller bearings to four to six rows and rows are removable,that the rings or a shoulder fixed and the roller can be mounted separately rings free, or that all components of working capital can be mounted separately. This simplifies the installation, maintenance and control. A certain axial displacement of the tree compared to the level can be tolerated in the rotation.

Roller four rows of cylindrical roller bearings SKF have a cylindrical bore, and some dimensions are available with a conical bore. Roller conical bore can be adjusted during assembly to get a certain radial internal or pre-defined.

You will find the data sheets of SKF maintenance and lubrication products in all types in SKF bearing datasheets. No matter they are SKF ball bearings( deep groove ball bearings, angular contact ball bearings, self-aligning ball bearings, thrust ball bearings ) or SKF roller bearings( cylindrical roller bearings, spherical roller bearings, tapered roller bearings, needle roller bearings ).

In the following I will take 22228 CCK/W33 — 1550532228 for example:

SKF spherical roller bearings have two rows of rollers with a common sphered raceway in the outer ring and two inner ring raceways inclined at an angle to the bearing axis. This gives them an attractive combination of design features making them irreplaceable in many demanding applications. They are self-aligning and consequently insensitive to misalignment of the shaft relative to the housing and to shaft deflection or bending.

The specifications of shperical roller bearings are as below:

Bearing Design
Type                     Spherical
Dimensions
Design Units          Metric
Bo re                    5.5118 inch
Outside Diameter   9.8425 inch
Overall Width        2.6772 inch
