The role is to make bearing with stationary bearing ring and the rotating ring are still some parts of the installation (usually housing) and the rotating part (usually the shaft) with consolidation, in order to achieve load transfer in the rotating state and limit movement position relative to the stationary system, the system's basic tasks.

The shaft and bearing, the bearing requirements in the radial, axial and tangential direction in three directions fixed its position. Radial and tangential orientation through the tight fit of the bearing rings taken to achieve the axial positioning only in rare cases, the use of a tight fit; generally limit the use of axial components, such as end caps and ring limit the axial position in the clearance range.

Should be selected with the focus on the following four points:

(1), bearing rings and the circumferential surface should be well supported even by force, to reduce distortion, and give full play to the carrying capacity of the bearing.

(2) With the surface of the ferrule in its direction can not slide along the tangent, otherwise it will damage the mating surface.

(3) The free end of the shaft and the bearing must be able to with the length of the housing bore adapt to changes that must adapt to the axial position within a certain range of swimming ability.

(4) Must be taken so that the bearing installation and removal easy, saving time and labor.
