Thrust ball bearings are divided into single and double
direction designs .The single direction bearings can only be used
to carry axial load in one direction and limit the axial load in
one direction and limit the axial displacement in single direction
.
The doulbe direction bearings can be used to carry axial loads
in both directions and limit the axial displacements in both
directions .
Neither can carry radial loads .
This type of bearings suitable for applications where the
rotational speed is lower .
In order to prevent detrimental movement centrifugal force
during bearing in high speed the requisite minimum axial load
should be applied .
