Radial bearing - a mechanism, which is part of the support shaft angle or other equipment. Bearing assumes by operation, which is directed perpendicular to the shaft axis. In modern times there is quite a large variety of bearings, which can take a different type of effort. 
types of bearings
Usually, everything bearings There are two types: sliding and rolling bearings. The first device type is a specific support, wherein the friction processes occur due to sliding surfaces. The second type of bearing design has inner and outer rings. Between data elements is a separator with rolling bodies. The outer ring is located in the housing and is fixed.
Depending on the application generally used:
- ball bearing,
- double row ball bearings,
- roller double row,
- angular contact bearings, and so on.
Single-row ball bearings
It is well-known device that can be purchased in the company Galpodshipnik. products receives force in a radial range and axle. Such devices may be performed by construction in a closed or open form.
Double row ball bearings
Such devices withstand the load via two rows of rolling bodies. Such mechanisms are heavier. To a significant advantage bearing structure data include the possibility of self-adjustment.
This group should highlight spherical roller bearings with two rows. Among these the most known arrangements include modifications 3500 or 3600. series 53500 and 53600 equipped with steel cages. Usually, Such devices are available with a cylindrical fit.
Angular contact bearings
These bearings are able to perceive the strong radial and axial forces. Generally these bearings are used to construct single and double row type. Very rarely used 4-row bearings of this type.
Ball-point angular contact bearings
Devices used for radial load, and if it is one-sided. These devices have very interesting design of the. Usually, is checked separator made of steel or brass.
Such mechanisms as roller angular contact bearings have in their equipment tapered rollers, which act as friction force. Bearings can take quite serious load, which is one of the significant advantages. But there is a certain lack of: low number of possible revolutions. Among this type of bearings have identified a number of series, which are classified according to their functions and have different characteristics. Often used series 7000.
These bearings can accommodate radial and axial loads. series 27000 – This bearings with high cone angle. In terms of features, such mechanisms are similar to the above series. series 77000 is a 4-row roller bearings, calculated on the perception of radial and axial forces is very small.
Conclusion
In this way, important to understand, that different bearings, on the basis of their design features and functions, They have different scope. In order to pick up that mechanism, which is needed, necessary to define, what function it has to perform. Also, when choosing a careful attention should be paid to the manufacturer of a particular bearing. It is unlikely that Chinese machinery will last a long time. Therefore, choose the best quality of the bearings enterprises of Alexander Tilman “Galpodshipnik”, which guarantee a long service life.
