Types of SKF Cylindrical Roller Bearing

There are several types of SKF cylinder roller bearing but the following two are the most important one is SKF cylindrical roller bearing with a single row other is a double row SKF cylindrical roller bearing.

SKF Cylindrical Roller Bearing With a Single Row
SKF cylindrical roller bearing with a single row has an N-type design. SKF cylindrical roller bearing with a single row consists of a cage, two inner rings that are fixed to maintain the single row of roller and it also has a single smooth ring on the outside to reduce friction. N-type cylindrical roller bearing may cause displacement up to certain limits when their shaft comes in contact with the house because such types of SKF cylindrical roller bearing allow axial misplaced that's why they are used bearings units which are non-located to upthrust the load capacity.
SKF Cylindrical Roller Bearing With a Double Row
SKF cylindrical roller bearing with a double row comes in various sizes and different designs. NNU and NN designs are used in double row SKF cylindrical roller bearing. The bearing design is typically depending upon the side ribs which are joined by either the inner ring or outer ring. SKF cylindrical roller bearing with a double row is used in automobile and precision machine equipment for preload as they are hard and possess radial rigidity at a higher rate.

SKF cylindrical roller bearings

The SKF cylindrical roller bearings are manufactured according to different designs since the load conditions are not the same in every application. There may be axial load at some places, radial load at other ones, or some applications require both the axial and radial loads. Similarly, there come situations where misalignment is a big issue. Therefore, the SKF cylindrical roller bearings are designed to deliver maximum performance under the aforementioned conditions with a minimum amount of internal stress. For Instance, the misalignment between the bearing assembly and shaft sometimes becomes a gigantic problem in the bearing world. To cater to this condition, the SKF cylindrical roller bearings are designed to work with a huge misalignment but to ensure that their service life will remain the same with noticeable degradations. Thus, the bearing arrangement can be selected as per the load conditions of the specific application.

Lubrication for SKF Cylindrical Roller Bearing

Lubrication

In every type of roller bearing, lubrication is the most significant part as it helps in smooth operation by reducing the amount of friction between the rollers and their paths. However, the chances of extra scrubbing of raceways and the rollers are less in SKF tapered roller bearings due to their configuration. When proper lubrication is done it has many other benefits apart from reducing friction as it helps in noise dampening and dissipation of heat. SKF cylindrical roller bearings are lubricated with lithium soap-based grease for a high level of corrosion protection.  SKF cylindrical roller bearings are also lubricated with oil lubricants.

SKF cylindrical roller bearing should be made of rusting-free material because rusting-free high-quality steel prevents SKF cylindrical roller bearing from corrosion.

Contamination Free Environment

SKF cylindrical roller bearing requires a contamination-free environment, as you know well dirt and dust from the surrounding may be trapped by ribs, rings, and cages of SKF cylindrical roller bearing. It will reduce the durability of bearings and bearings may flake or cracked earlier.

Perfect Alignment

SKF cylindrical roller bearing requires perfect alignment. All of the bearing parts like the cage, ribs, and inner and outer rings should be properly aligned because misalignment may lead to the failure of the SKF cylindrical roller bearing.

Low Thrust Load

Thrust load should be low because SKF cylindrical roller bearing does not tolerate much thrust load even at very high speed but can bear high radial load.  So, if the load is increased it will cause resonance that is critical and greatly affects the roller’s life Because of resonance the roller’s end experienced an excessive dynamic force that is transmitted by the resonance effect. So, it is needed to decrease resonance the thrust load should be reduced to avoid this issue.

Manufacturing and Substances Used for SKF Cylindrical Roller Bearing

Substances that are used to manufacture SKF cylindrical roller bearing are used according to their application because some applications require high carbon amounts, and high-quality steel to tolerate high radial load. Typically, SKF cylindrical roller bearing is formed by steel alloys. Some SKF cylindrical roller bearing does not require a high carbon quantity of steel, and such types of SKF cylindrical roller bearing can be hardened by providing heating induction or using small bearing heaters so they can be introduced into machinery to a sufficient depth to sustain thrust load. For proper hardness and corrosion resistance cases additional carbon and alloys of steel are used. Some SKF cylindrical roller bearings don’t require a cage and some have come on the market with different cage sizes. Cage for SKF cylindrical roller bearing is generally made of brass or pressed steel. But it is not necessary because cages with molded polyamide are also formed, and available on market, however, which material is used for cage formation is dependent on applications of SKF cylindrical roller bearing. SKF cylindrical roller bearing without cage allows high load capability but at very high speed. There are several SKF cylindrical roller bearings which are come without ribs the presence and absence of ribs depending on the series. Some SKF cylindrical roller bearings do not have any ribs on either ring inner or outer, so, in such cases, both inner and outer rings relatively move. Such types of SKF cylindrical roller bearing offer free end bearing services and are used in various applications to lift the high radial load.
