The following are the three main types of bearings, depending on the type of load bearing, ie axial, axial load, radial load radial and mixed for radial and axial letters.

Radial bearings:

Bearing groove ball type have many applications. They are very simple construction, high strength and easy maintenance. May be one or two balls caminaos and can provide sealed or open.

By having areas such as rolling element, friction is very small, so they are widely used in situations requiring high speeds.

Are a type of bearing radial, ie mainly supporting radial loads, but also have the ability to withstand small axial loads.

Bearings mixed:

The ball bearings of angular contact type, the raceways are oblique to the axis, so that both support, radial and axial loads. Because of this, to prevent axial movement must be placed two opposite each other

This type of bearing is arranged a special finish called Xlife, these tracks are better quality and rolling balls too, so you get a bearing with a 50% longer life than normal execution.

Axial:

Other types of bearings are thrust bearings that support only axial loads, ie loads parallel to the axis is supported by the bearing. Axial ball bearings consist of two shaft ring, two rings of housing and a ball corana. This type of bearing only held together after assembly, ie, different parts can be mounted separately.

There are of this type with flat discs with spherical housing rings, to compensate for errors in the alignment of the shaft to be supported. These types are usually combined with the use of a backplate.

Also may be of single or double acting also. Both support very high axial loads but no axial loads.
